Electrostatics question

2022 · 26 Jun · Shift 1 · Q51

JEE MainPhysicsElectrostaticsMCQ+4 / −1
Given below two statements : One is labelled as Assertion (A) and other is labelled as Reason (R). Assertion (A) : Non-polar materials do not have any permanent dipole moment. Reason (R) : When a non-polar material is placed in an electric field, the centre of the positive charge distribution of it's individual atom or molecule coincides with the centre of the negative charge distribution. In the light of above statements, choose the most appropriate answer from the options given below.
  1. A
    Both (A) and (R) are correct and (R) is the correct explanation of (A).
  2. B
    Both (A) and (R) are correct and (R) is not the correct explanation of (A).
  3. C
    (A) is correct but (R) is not correct.
  4. D
    (A) is not correct but (R) is correct.
