Acceleration v/s displacement graph of a particle moving in a straight line is as shown in the figure. The initial velocity of the particle is zero. The velocity v/s displacement graph of the particle would be :

Options

A.
B.
C.
D. None of these

Answer

C

Explanation

a = ks [k = positive constant]
`(vdv)/(ds)=ks`
`intvdv = kintsds`
`(v^(2))/(2)=(ks^(2))/(2)`
`v = sqrt(k)s`
