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(3) ms^(-2)`

B

`3sqrt(3) ms^(-2)`

C

`sqrt(3) ms^(-2)`

D

`4//sqrt(3) ms^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
A
a. `a = v(dv)/(dx) = 4 xx (-tan60^@) = -4sqrt(3) ms^(-2)` .
