Two identical particles `1` and `2` are projected from surface of earth with same velocities in the directions shows in figure.

A

Both the particles will stop momentarily (before striking with ground)at different times

B

Particle `-1` will rise upto lesser height compared to particle`-2`

C

Minimum speed of particle`- 2` is more than that of particle`-1`

D

Particle `-1` will strike the ground earlier

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
At heighest point velocity of particle-1 will becomes zero. But velocity of particle-2 is non zero.
