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

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

A

both particles will reach at ground simultaneously

B

both particles will reach at ground with same speed

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
A
For both cases `t = sqrt((2h)/(g)) =` constant. Because vertical downward component of velocity will be zero for both the particles.
