if a proton and an electron are released when they 2.0 x 10^-10 m apart, find the initial acceleration of each of them

Answer 1

acceleration=force/mass

so the force is the same, but mass is different

Answer 2

I know a=ke^2/mr^2
K= 8.99 * 10^9
e= 1.6 *10^-19
r= 2.0 *10^-10
so, what is the m ?

Answer 3

Use Coulombs law, then F=ma. When using F=ma, use the F that you found from solving coulombs.
