Question

Calculate the minimum electrostatic force between two charged particles separated at a distance of 1 cm in air?

Answer 1

Explanation:

Your distance, r, is constant here so the Force will depend on the charge. Minimum possible magnitude will occur when the force acting on the charge is at a minimum, i.e. the charge of one electron.

Your q1 = q2= e = 1.6 x 10-19C

Convert the r at 1cm to m, 1 x 10-2m, because your units for Newtons have m2

Set the Force equation and plug in your values including the constant: F = kq1q2/r2
