Suppose two alpha particles were held together so they were just touching.
a. Estimate the electrostatic repulsive force each would exert
on the other.
Express your answer
using two significant figures.
b. What would be the acceleration of an alpha particle subjected
to this force?
Express your answer
using two significant figures.
Homework Answers
Here both particles are positively charged so there is a force
of repulsion between them.
The magnitude of this force of repulsion is given by Coulomb
