If a point charge be rotated in a circle of radius r around a charge q. what will be the work done?

If a point charge is rotated in an arc of radius r around a charge q, what will be the work done. Explain.

If a point charge is taken throgh some distance in a circle around a charge q, what will be the the work done?

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 test charge (+q) moved 10 times along a circular path of radius r with a charge + Q at the centre. The work done is

STATEMENT -1 : A point charge be rotated in a circle around a fixed charge, the work done by electric field of fixed charge will be zero. and STATEMENT -2 : Work done is the dot product of force and displacement.

STATEMENT -1 : A point charge be rotated in a circle around a fixed charge, the work done by electric field of fixed charge will be zero. and STATEMENT -2 : Work done is the dot product of force and displacement.

A charge of 100 esu is placed at a point. What will be the amount of work done (ii) To carry a unit positive charge once, along a circle of radius 10 cm around the given charge? Answer with reasons.
