Question

29. A particle A having a charge of 2.0 X 10C is held fixed
on a horizontal table. A second charged particle of mass
80 g stays in equilibrium on the table at a distance of
10 cm from the first charge. The coefficient of friction
between the table and this second particle is u=0.2.
Find the range within which the charge of this second
particle may lie.​
