ANSWER

Let the charge of proton is q

Charge of α−particle

=2×chargeofproton

=2q

The force acting between two protons separated by a distance r is

F'=k q⋅q/r^2=k q^2/r^2

The force acting between two α− patricles separated by a distance 2r is

F ′=k 2q⋅2q/(2r) ^2

=k 4r^2/4q^2

or =k r ^2\r^2

⇒F '=F
