A particle is moving along a straight line whose velocity - displacement graph is shown in figure. What is the acceleration when displacement is 3 m?

A

` -4sqrt 3m//s^(2)`

B

` 3sqrt3m //s^(2)`

C

` sqrt3 m//s^(2)`

D

` (4)/(sqrt( 3)) m//s^(2) `

Text Solution

Verified by Experts

The correct Answer is:
A
` a=v (dv)/( dx) =vxx ` (slope in v-x graph ) `=4xx (-tan 60^(@) ) =-4sqrt3 ms^(-2) `
