JEE Main 12 April 2023, Shift 1, Physics Q41

Question 41 of 90 in this shift, Physics question 11 of 30, Section A.

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 30×10−530\times10^{-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.
  1. (1)Both A and R are true and R is the correct explanation of AOfficial answer
  2. (2)Both A and R are true but R is NOT the correct explanation of A
  3. (3)A is true but R is false
  4. (4)A is false but R is true
