The displacement-time graph for two part...

The displacement-time graph for two particles A and B are straight lines inclined at angles of `30^(@)` and `60^(@)` with the time axis. The ratio of velocities of `V_(A) :V_(B)` is

A

`1:2`

B

`1:sqrt3`

C

`sqrt3 :1`

D

`1:3`

Text Solution

Verified by Experts

The correct Answer is:
D
Velocity = Slope of displacement  Time graph ` = tan theta`
`v_A/v_B = (tan theta_A)/(tan theta_B) = (1//sqrt3)/(sqrt3) = 1/3`
