Two projectile A and B located at (0,0) ...

Two projectile A and B located at (0,0) and (4.4) respectively start moving simu ltaneou lsy with velocities `V_(A)=-4hati` and `V_(B)=4hatj`:

A

the shortest distance between them is `4sqrt(2)m`

B

the shortest distance between them first decreases and then increases

C

the distance between them increases from the beginning

D

the magnitude of relative velocity of A w.r.t. B is 4m/s

Text Solution

Verified by Experts

The correct Answer is:
a,b
Horizontal range =VxxT
Since the 2nd particle is projected after 2s.
Hence the particles will reach the ground in an interval of 2s.
