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

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:

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 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:

If an electron moves from rest, from a point at which potential is 60 volt to another point at which potential is 110 volt, then its kinetic energy in the final state will be
