A particle (A) is dropped from a height ...

A particle (A) is dropped from a height and another particle (B) is thrown in horizontal direction with speed of 5 m/s from the same height. The correct statement is

A

Particle (A) will reach at ground first with respect to particle (B)

B

Particle (B) will reach at ground first with respect to particle (A)

C

Both particles will reach at ground simultaneously

D

Both particles will reach at ground with same speed

Text Solution

Verified by Experts

The correct Answer is:
C

For particle (A)
`h=1/2"gt"^2`
`t_A=sqrt((2h)/g)`
For particle (B) In vertical direction
use `s=ut +1/2at^2`
`rArr h=1/2 g t_B^2rArr t_B=sqrt((2h)/g)`
