Physics Motion in a Straight Line Motion Under Gravity Single Correct MCQ

Published on: September 13, 2026

An aeroplane is moving with a velocity u . It drops a packet from a height h . The time t taken by the packet in reaching the ground will be

\(\sqrt{\left(\frac{2gh}{l}\right)}\)

\(\sqrt{\left(\frac{2u}{g}\right)}\)

\(\sqrt{\left(\frac{2h}{g}\right)}\)

\(\sqrt{\left(\frac{2h}{a}\right)}\)

Text Solution

Verified by Experts

The correct answer is:

The initial velocity of aeroplane is horizontal, then the vertical component of velocity of packet will be zero.

So \(t = \sqrt{\frac{2h}{g}}\)
