The velocity-time graph of a body is shown in figure. The ratio of magnitude of average acceleration during the intervals OA and AB is

A

`1`

B

`(1)/(2)`

C

`(1)/(3)`

D

`3`

Text Solution

Verified by Experts

The correct Answer is:
C
During OA, acceleration `=tan30^(@)=(1)/(sqrt(3))ms^(-2)`
During AB, acceleration `=-tan60^(@)=-sqrt(3)ms^(-2)`
requried ratio `= (1//sqrt(3))/(sqrt(3))=(1)/(3)`
