There is a fixed positive charge Q at O and A and B are points equidistant from O. A positive charge + q is taken slowly by an external agent from A to B along the line AC and the along the line CB.

Answer»

The TOAL work DONE on the charge is zero
The work done by the electrostatic force from A to C is negative
The work done by the electrostatic force from C to B is positive
The work done by electrostatic force in taking the charge from A to B is dependent on the ACTUAL path followed

Answer :A::B::C
