Assertion: A constant force F is applied...

Assertion: A constant force F is applied on two blocks and one spring system as shown in figure. Velocity of centre of mass increases linearly with time.

Reason: Acceleration of centre of mass is constant.

A

(a) If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

(b) If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

(c) If Assertion is true, but the Reason is false.

D

(d) If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
`a_(CM)=(F)/(3m)=cosnt ant`
`:. `v_(CM)=a_(CM)t=(F)/(3m)t`
or `v_(CM)prop t`
