Assertion(A): A point charge q is rotated along a circle around another point charge Q .The work done by electric field on the field on the rotating charge in half revolution is zero. Reason (R ) :No work is done to move a charge on an equipotential line or surface.

A point charge Q is moved along a ciruclar path around another fixed point charge. The work done is zero

Statement-I : A point charge Q is rotated in a circle of radius r around a charge q. The work done will be zero. Statement-II : For this motion the force is along the radius and direction of motion is perpendicular

A point charge q is kept at a corner of a cube

A positive point charge q_(1) is placed at (a,0) and another positive point charge q_(2) is placed at (0,a) . Find the force acting on q_(1) .

Inside a neutral hollow conducting sphere of radius X and centre C, a point charge q is placed as shown in the figure. Another point charge q_1 , is placed outside the sphere at distance d from centre. The net- electrostatic force on charge q placed at the centre is K=1/(4piepsilon_0)
