Solution

Q.
Given below are two statement: one is labelled as Assertion A and the other is labelled as Reason R.

Assertion A: If an electric dipole of dipole moment $30 \times 10^{- 5} Cm$ is enclosed by a closed surface, the net flux coming out of the surface will be zero.

Reason R: Electric dipole consists of two equal and opposite charges.

In the light of above statements, choose the correct answer from the options given below: [2023]

1 Both A and R are true and R is the correct explanation of A

2 A is true but R is false

3 Both A and R are true but R is NOT the correct explanation of A

4 A is false but R is true

Ans.
(1)

$\vec{P} = 30 \times 10^{- 5} Cm$

$Using Gauss law$

$ϕ = \frac{Q_{in}}{ε_{0}} and Q_{in} = 0 \Rightarrow ϕ = 0$
