Assertion: A balloon ascends from the su...

Assertion: A balloon ascends from the surface of earth with constant speed. When it was at a height `50 m` above the ground, a packet is dropped from it. To an observer on the balloon, the displacement of the packet, from the moment it is dropped to the moment it reaches the surface of earth, is `50 m`
Reason: Displacement (vector) depends upon the reference frame used to measure it.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If assersion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
To an observer on the balloon, the ground is moving.
