Read the following paragraph and answer the questions:
Total amount of work done in bringing the different charges to their respective positions from infinitely large mutual separation is defined as Electrostatic potential energy of a system.
Work done in carrying charge to any point from infinity is product of potential and charge:
W Potential `xx` Charge
This work is stored in the system of two point charges in the form of electrostatic potential energy U of the system.

In a uniform electric field, a positively charged particle is released from rest. The electric potential energy of the charge:

Options

A. Decreases because the charge moves opposite to electric field
B. Increases because charge move along the electric field
C. Decreases because the charge moves along the electric field:
D. Remains constant

Answer

C

Explanation

decreases because the charge moves along the electric field
Explanation: The positively charged particle experiences electrostatic force along the direction of electric field, ie, from high electrostatic potential to low electrostatic potential. Thus, the work done by the fieldon the positive charge, hence electrostatic potential energy of the positive charge decreases.
