Two straight lines drawn on the same displacement-time graph make angles `30^(@)` and `60^(@)` with time-axis respectively Fig. 2 (a) .36 Which line represents greater velocity? What is the ratio of two velocities?
.

A

` 1:2`

B

` 1:3`

C

` 2:1`

D

` 3:1`

Text Solution

Verified by Experts

The correct Answer is:
D
The slope of displacement-tiem graph is the velocity of the body. ltbr gt ` v-1 v_2 = ( tan 60^@)/(tan 30^@) = (sqrt 3)/(1 //sqrt 3) = 3`.
