An alpha particle charge 2.0e is sent at high speed toward a gold nucleus charge 79e What is the electrical force acting on the alpha particle when it is 3.0 10-14 m from the gold nucleus?

Assuming a positive charge on the Alpha particle...
F = (Q1*Q2)/(r2)*K
F = (158e2)/(3*10-14)2*(8.988*109)
F = 40.4951176224... N = 40N
Edit....
F=ke(q1)(q2)
r^2
=(8.99x109 N*m2/C2) (158x1.60x10-19C)2 / (2.0X10-14m)2
=91N (the m2and C2 cancels out)Wiki User

What is the electrical charge of an alpha particle?
The electric charge of an alpha particle is positive. An alpha particle is a helium nucleus (which being a nucleus has a positive charge)
Particle found in the nucleus of an atom which carries no electrical charge?
That would be the neutron
Subatomic particle with a charge of plus 1?
proton, in nucleus
What particle has no electrical charge?
neutron. if your talking about radiation, gamma
Which subatomic particle gives the nucleus its electric charge?
The proton (which is positive).
What is the particle in the nucleus of the atom with no electrical charge?
Neuton does not have any charge
What bears a positive electrical charge while what has no electrical charge?
The proton is the particle that has a positive charge. The neutron is the particle that has a neutral charge. both of these reside in the nucleus of an atom.
What subatomic particle has no net charge?
In the atomic nucleus the neutron has no electrical charge.
What is a small particle in the nucleus of an atom with no electrical charge?
neutron
What is the electrical charge of an alpha particle?
The electric charge of an alpha particle is positive. An alpha particle is a helium nucleus (which being a nucleus has a positive charge)
Lacking electrical charge?
The neutron, a subatomic particle inside the nucleus of an atom, does not have a charge.
What lacking electrical charge?
The neutron, a subatomic particle inside the nucleus of an atom, does not have a charge.
Particle found in the nucleus of an atom which carries no electrical charge?
That would be the neutron
What is a subatomic particle having zero charge found in the nucleus of an atom?
This particle is the neutron.
A particle in the nucleus of an ATM it has a positive electrical charge and is 2000 times that of the electron?
A proton
What is a particle with a positive electrical charge of 1 unit that exists in the nucleus of an atom?
The proton.
