On moving a charge of 7C from a point x where potential is +5.5V to a point y where potential is -7.6 V, the work done is -

If 20 J of work has to be done to move an electric charge of 4 C from a point, where potential is 10 V to another point, where potential is V volt, find the value of v.

The work done in moving a charge of 2 xx 10^(-9) C from a point of potential - 3000 V to another point P is 5 xx 10^(-5) J . Find the potential at the point P.

If 100 J of work must be done to move electric charge equal tp 4C from a place where potential is -10V to another place where potential si V volt, find the value of V.

If 10 J of work is to be done in moving a charge of -200C from A to B, which of the two points is at higher potential ? What is the potential difference ?

Some work is done to move a charge Q from infinity to a point A in space. The potential of the point A is given as V. What is the work done to move this charge from infinity in terms of Q and V?

A small particle has charge -5.00muC and mass 2.00 xx 10-4 kg. It moves from point A where the electric potential is V_A = +200 V . to point B, where the electric potential is V_B=+ 800 V . The electric force is the only force acting on the particle. The particle has speed 5.00 m/s at point A. What is its speed at point B? is it moving faster or slower at B than at A. Explain,

The work done in moving a charge from one point to the other is 20J. If the potential difference between the points is 10V, the charge is:
