In displacement time graph, two straight lines make angles `60^(@) and 30^(@)` with time axis. The ratio of mangnitudes of the velocities represented by them is

A

`1 : 2`

B

`1: 3`

C

`2 : 1`

D

`3 : 1`

Text Solution

Verified by Experts

The correct Answer is:
D
`(v_(1))/(v_(2)) = (tan 60^(@))/(tan 30^(@)) = (sqrt(3))/(1//sqrt(3)) = (3)/(1)`
