Two charges `Q_(1)` and `Q_(2)` coulombs are shown in figure. A third charge `Q_(3)` coulombs is moved from points R to S along a circular path. Change in potential energy of the charge is -

Two charges Q_(1) and Q_(2) Coulombs are shown in fig. A third charge Q_(3) coulomb is moved from point R to S along a circular path with P as centre Change in potential energy is

Two charges q_(1) and q_(2) are placed 30 cm apart, as shown in the figure. A third charge q_(3) is moved along the arc of a circle of radius 40 cm from C to D . The change in the potential energy o fthe system is (q_(3))/(4pi epsilon_(0))k ., where k is

The value of charge q_1 ,q_2 and q_3 as shown in the figure are

2q and 3q are two charges separated by a distance 12cm on x-axis .A third charge q is placed at 5cm on y-axis as shown in figure .Find the change in potential energy of the system if 3q is moved from initial position to a point on X-axis in circular path
