The displacement-time graphs of two moving particles makes anlges of `30^(@)` and `45^(@)` with the X-axis.The ratio of their velocities is

A

`sqrt(3):2`

B

`1:1`

C

`1:2`

D

`1:sqrt(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
Slope of displacement-time graph gives velocity

`therefore(v_(1))/(v_(2))=(tantheta_(1))/(tantheta_(2))=(tan30^(@))/(tan45^(@))=(1)/(sqrt(3))`
