A particle `A` having a charge `10 mu C` is held fixed on a horizontal surface. A block of mass `80 g` and having charge stays in equilibrium on the surface at a distance `3 cm` from the first charge. The coefficient of friction between the surface and the block is `mu = 0.5`. Find the range within which the charge on the block may lie.

A particle A having a charge of 2.0xx10 ^(-6) C is held fixed on a horizontal table. A second charged jparticle of mass 80g stays in equilibrium on the table at a distance of 10 cm from the firsst charge.
