Assertion : A shell at rest, explodes. The centre of mass of fragments moves along a straight path.
Reason : In explosion the linear momentum of the system remains always conserved.

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 the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
As the shell is initially at rest and after explosion, according to law of conservation of linear momentum, the centre of mass remains at rest. While parts of shell move in all direction, such that total momentum of all parts is equal to zero.
