Question

11) Which statements are true for an electron moving in the direction of an electric field?

A) Its electric potential energy increases and the electric potential decreases

B) Its electric potential energy decreases and the electric potential decreases

C) Its electric potential energy decreases and the electric potential increases

D) Its electric potential energy increases and the electric potential increases

Answer 1

For an electron moving in the direction of an electric field

It electric potential energy will increase and the electric potential decreases

Correct option is A.

Since we know that

E = -V/d

So as we moves in the direction of electric field it's electric potential will decrease.

Now Since electric potential energy is given by:

EPE = q*V

Since V is decreases and charge on electron is negative, So EPE will increase. In other word since electron is moving from high to low potential, So it's EPE will increases.
