Two particles A and B are projected simultaneously in the directins shown in figure with velocities `v_(A) = 20 m//s and v_(B) = 10 m//s` respectively. They collide in air after `1/2` s. Find
(a) the angle `theta`
(b) the distance x.
.

A

`2sqrt3 m`

B

`3sqrt3 m`

C

`4sqrt3 m`

D

`5sqrt3 m`

Text Solution

Verified by Experts

The correct Answer is:
D
From 2 `20 sin theta=10, sin theta =1/2`
`theta=30^(@),(20cos 30)1/2=x`
`x=5sqrt3m`
