What is the charge of a positron in coulombs?
The charge of a positron is equal in magnitude but opposite in sign to that of an electron. Therefore, the charge of a positron is approximately 1.6 x 10^-19 coulombs.
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?
The anti-matter equivalent of an electron is a positron. Positrons have the same mass as electrons but have a positive charge. When a positron and an electron collide, they annihilate each other, releasing energy in the form of gamma rays.
What is the particle which is opposite in charge to the electron?
The particle that has the opposite charge of an electron is the proton. The electron has a charge of -1 while the proton has a charge of +1. (Though they have equal - but opposite - charges, the proton is about 1836 times more massive than the electron.) It might be worth mentioning that the antiparticle of the electron, the positron, also has a charge of +1. And it (the positron or antielectron) has a mass identical to the electron's. (An antielectron, the positron, will combine with an electron when the pair are at low energy in an annhilation event. Both particles will have their masses converted into energy.)
The collision of one electron and one positron produces one or two photons?
This supposition is not true. Mutual annihilation, which occurs when a positron combines with an electron, will result in the conversion of all of the mass of both particles into energy. And this will result in the formation of two photons. The production of the photon pair is the result of conservation laws, and the two photons leave the event in opposite directions.

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.
What is the antiparticle of a positron?
The antiparticle of a positron is an electron. Both the positron and electron have the same mass but opposite charge, with the positron having a positive charge and the electron having a negative charge.
What is The ratio of the specific charge of an electron to that of a positron is?
The ratio of the specific charge of an electron to that of a positron is 1:1. Both the electron and positron have the same magnitude of charge but opposite in sign, with the electron being negative and the positron being positive.
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.

Does the positron has the same charge as an electron?
No, although their respective charges are exactly equal in size, they are opposite in sign.
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.
What is the charge of a positron in coulombs?
The charge of a positron is equal in magnitude but opposite in sign to that of an electron. Therefore, the charge of a positron is approximately 1.6 x 10^-19 coulombs.
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 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).
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".
