Explanation:
I TOOK A TEST ON THIS QUESTION
Answer:
F = 91.27 N
Explanation:
Parameters given:
Charge of alpha particle, q = +2.0e =
= 
Charge of gold nucleus, Q = +79e =
= 
Distance between the alpha particle and gold nucleus, r = 
Electric force is given as:
F = 
where k = Coulomb's constant
Therefore:

The electric force acting on the alpha particle when the alpha particle is
from the gold nucleus is 91.27 N.
