Question

. Calculate the coulombic force acting between an electron and a proton kept

separated by a distance of 8 × 10−10 apart. ​

Answer 1

Explanation:

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

r
