IN a conductor, a point P is at higher potential than another point Q. In which direction do the electrons move?

If an electron moves from rest from a point at which potential is 50 volt to another point at which potential is 70 volt, then its kinetic energy in the final state will be

An object is taken from a point P to another point Q in a gravitational field:

A particle of mass m and positive charge q is released from point A. Its speed is found to be v when it passes through a point B. which of the two points is at higher potential ? What is the potential difference between the points?

In section PQ of a circuit P is at higher potential than Q by 40 V. The potential difference in volt across the battery A is:

In the given circuit potential of the point A is 9 V higher than potential of the point B. Choose correct alternative (s)

In Figure if the potential at Point P is 100 V , what is the potential at point Q?
