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.
