Two small charged spheres contain charge +q_(1) and +q_(2) respectively. A charge dq is removed from sphere carrying charge q_(1) and is transferred to the other. Find charge on each sphere for maximum electric force between them.

Two conducting spheres of radii r_(1) and r_(2) having charges Q_(1) and Q_(2) respectively are connected to each other. There is

Two sphere M and N, having charge q_(1) and q_(2) are kept at some distance from each other.q amount of charge is taken from the sphere M and transferred ot the sphere N. What is the new charge of the two spheres so that the force acting between them becomes maximum?

A conducting sphere of radius R and carrying a charge Q is joined to an uncharged conducting sphere of radius 2R . The charge flowing between them will be

A conducting sphere of radius R and carrying a charge Q is joined to an uncharged conducting sphere of radius 2R . The charge flowing between them will be

There are two spheres of radii R and 2R having charges Q and Q//2 , respectively. These two spheres are connected with a cell of emf V volts as show in. When the switch is closed, find the final charge on each sphere.
