Which of the following statements is true about electric potential V?

If a point charge produces V, it will also experience a force due to that V

If the electric field is uniform in a region of space, then V has the same value at each point in this region

Electric potential and electric potential energy are equal for positive point charges

A negative point charge in a potential V produced by other point charges tends to move to a position where V is higher if there are no external forces opposing this movement

all of the statements are true
