Assertion : The centre of mass of an electron and proton, when released moves faster towards proton.
Reason : This is because proton is lighter than electron.

A

If both, Assertion and Reason are true and the Reason is the correct explanation of the Assertion.

B

If both, Assertion and Reason are true but Reason is not a correct explanation of the Assertion.

C

If Assertion is true but the Reason is false.

D

If both, Assertion and Reason are false.

Text Solution

Verified by Experts

The correct Answer is:
D
The position of centre of mass of electron and proton remains at rest, as their motion is due to (internal) forces of electrostatic attraction, which are conservation. No external force, whatsoever is acting on the two particles. Also, proton is not lighter than electron. choice (d) is correct.
