Question

Physics Question on Electrostatics

Given below are two statements
Statement-I: A point charge is brought in an electric field. The value of electric field at a point near to the charge may increase if the charge is positive.
Statement-II: An electric dipole is placed in a non-uniform electric field. The net electric force on the dipole will not be zero.
Choose the correct answer from the options given below.

A

Both statement-I and statement-II are true

B

Both statement-I and statement-II are false

C

Statement-I is true but statement-II is false

D

Statement-I is false but statement-II is true

Answer

Both statement-I and statement-II are true

Explanation

Solution

The correct answer is (A) : Both statement-I and statement-II are true
As one moves closer to a positive charge (isolated) the density of electric field line increases and so does the electric field intensity
⇒ Statement I is true

As opposite poles of an electric dipole would experience equal and opposite forces so net force on a dipole in a uniform electric field will be zero
⇒ Statement II is true
