Not necessarily. They always have opposite electric charges, but you can certainly
shoot them both in the same direction through a tube. If they then encounter a
magnetic field in the tube, it's true that then they'll curve in opposite directions.

What is the mass number of a positron?
The mass of a positron is approximately 9.1093826(16) × 10−31 kg. The positron and the electron are anti-particles of each other, and you can find out more about the positron at the Wikipedia article on that subject. A link to their post can be found below. There is also a link to a related question on the nature of the positron. That's down there, too.
What is the anti-matter equivalent of an electron?
No. The antiparticle for the proton is called antiproton. The antiparticle for the electron is called antielectron, also known as positron.
The rest mass energy of an electron positron pair is?
Twice the mass of the electron, since the positron has the same mass of the electron. Or the equivalent, in energy units.An electron has a mass or energy of 511 keV.
What is the symbol for a positron?
A positron is the antiparticle of the electron. We write the electron as e- as it is negatively charged. We write e+ or β+ for the positron. The latter symbol uses the Greek letter beta as positron emission is one of the two forms of the radioactive decay known as beta decay. Links can be found below.
What can positrons do?
Positrons are anti-electrons; they're antimatter. There are a couple of sources of positrons, and in our universe, the positron is looking for an electron to combine with so it can return from whence it came. This process, called mutual annihilation, sees the positron combine with the electron to produce two fairly high energy gamma rays (leaving the scene in opposite directions). In another universe, an antimatter one, the positron orbits around antimatter atomic nuclei. It also forms positricity in that universe. The positron is also used in medical imaging in positron emission tomography (PET) scans. The positron doesn't have a lot of penetrating power, and it won't travel far after it is released. But it is worth noting that those gamma rays that are released when a positron and an electron mutually annihilate each other are pretty high energy ones. They have a lot of penetrating power, and they can do considerable biological damage if a living thing is exposed to a positron source for too long. The PET scan only ends up "minimally exposing" an individual during the procedure, in case you're wondering. Links can be found below for more information.
How is a positron different from an electron?
A positron is an electron's antiparticle. It has the same mass as an electron, but an opposite electrical charge.
Is a proton the opposite of a electron?
No. The opposite of an electron is an antielectron or positron, which has exactly the same mass but opposite charge. A proton has opposite charge from that of an electron, but it is about 1836 times more massive.
Why do electron n positron move in opposite directions in pair production and how does momentum is conserved when they move in opposite directions?
They move in opposite directions when in a magnetic field because they have opposite charges. The force on a particle depends on its charge -- make the charge completely opposite, and the force on it will be completely opposite. Momentum is conserved when they move in opposite direction (that is, in their center of mass frame) because their respective masses are identical. One electron mass moving in one direction plus one electron mass moving in the opposite direction means a total momentum of zero. The system begins with zero momentum and ends that way.
Why isn't electron and positron mass equal?
Their masses are equal. It's their charges that are opposite.
Are the rest mass of the positron and the electron exactly equal?
Yes; they simply have opposite charges.
What is the antiparticle of a positron?
Since the positron is the antiparticle of the electron, it follows that the electron is the antiparticle of the positron.
Does positron have a negative charge?
A POSITron has a POSITive charge, hence the name. A positron is an anti-electron; since the electron has a negative charge, the positron has a positive charge.A POSITron has a POSITive charge, hence the name.

What is a particle with a positive chatge?
A beta particle is an electron, and electrons are negative. You're probably thinking of a positron, which has the same mass as an electron but the opposite charge.
Another name for positive charge?
The usual term is "positron." It's the antiparticle of an electron, having the same mass but opposite charge and opposite "electron number".
What would happen if a positron met an electron?
When a positron meets an electron, they annihilate or destroy each other.This phenomena is known as annihilation of matter. During this process two photons of gamma rays are produced that travel in opposite directions.Actually the mass of electron and positron has been converted into energy (gamma rays).
What is the difference between a positron and an electron?
An electron is the carrier of the negative electrostatic force, and it has a charge of -1. Also, the electron, along with the proton and neutron, are the "basic building blocks" of atoms, and they make up the matter all around us. The positron, on the other hand, is an anti-electron - it's antimatter! And it is the antiparticle of the electron. It has a charge of +1, which is just the opposite of the electron's. The fact that the electron and positron are matter and anti-matter, and that they have a charge of -1 and +1 respectively are the major differences. A positron is an electron's anti-particle, and when the electron and positron come in contact with each other to combine, they annihilate each other in a process called electron-positron annihilation. There is a link below to that related question and to a couple of others.
What is the antimatter version of an electron?
positron
