Question

A moving electron approaches another electron. What will happen to the potential energy of this system ?(A) will remain constant
(B) will increase(C) will decrease
(D) may increase or decrease

Answer 1

Answer:

(B) will increase

Explanation:

If an electron is brought closer to another electron, as the distance between them decreases, the electrical potential energy will increase. Electric potential is inversely proportional to the range and the research carried out is inversely proportional to the distance square.

Since, the electron is charged negatively, thus when it is brought close to another electron, a repulsive force is generated between them because of the same adverse charge. Hence, an action is performed against this repulsive force to bring them nearer and is placed in the form of potential electrostatic energy which also improves the system's electrostatic potential energy.

Answer 2

Answer:

option {B}

Explanation:

eill increase
