Statement I:A uniformly charged disk has a pin hole at its centre. The electric field at the center of the disk is zero.
Statement II: Disk can be supposed to be made up of many rings. Also, electric field at the center of a uniformly charged ring is zero.

A

Statement I is true, Statement II is True, Statement II is a correct explanation for statement I.

B

Statement I is true, Statement II is True, Statement II is Not a correct explanation for statement I.

C

Statement I is True, Statement II is False.

D

Statement I is False, Statement II is True.

Text Solution

Verified by Experts

The correct Answer is:
A
The electric field due to disk is superposition of electric field due to its constituent rings as given in reason. Assertion is true reason is true, reason is a correct explanation for assertion.
