Two charged particles are a distance 1 mm apart. Find the minimum Coulomb force between them.

Text Solution

Verified by Experts

As, ` F = (kq_1q_2)/(r^(2))`
For minimum Coulomb.s force,
` q_1 = q_2= e = 1.6 xx 10 ^(-19) C `
` rArr " " F = (9 xx 10 ^(9) xx (1.6 xx 10 ^(-19))^(2))/((10^(-3))^(2)) = 2.3 xx 10 ^(-22) N`
