NEETPhysicsElectrostatics
Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R . Assertion A : If an electric dipole of dipole moment 30 × 10 – 5 C m 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.
Options
- ABoth A and R are true and R is the correct explanation of A
- BA is false but R is true
- CA is true but R is false
- DBoth A and R are true and R is NOT the correct explanation of A
Correct answer
A. Both A and R are true and R is the correct explanation of A
Step-by-step solution
An electric dipole contains two equal and opposite charges. Thus, the net charge, as viewed from outside a surface enclosing the dipole, is zero. The net flux enclosed by any closed surface is, then, given by ϕ = q enc ε 0 = 0
