An Alpha Particle (Charge = +2e)is Sent at High Speed

Short Answer

An alpha particle (charge = +2e)is sent at high speed toward a gold nucleus (charge +79e).What is the electrical force acting on the alpha particle when it is at a distance of 2 *10 ^{- 14} m away from the gold nucleus? (e = 1.6 *10 ^{- 19} C)
