Answer 2

Answer:

ASSERTION : If we drop a stone and a sheet of paper from a balcony of first floor, then the stone will reach the ground first.

REASON : The resistance due to air depends on velocity only.

Assertion (A) is true but Reason (R) is false.

Explanation:

Gravitational acceleration is independent of the object's mass. Because of air resistance, a stone and a feather dropped from the same height do not reach the ground at the same time.
