The displacement of a body along the x-axis depends on time as `sqrt(x)=t+2`, then the velocity of body

A

increases with time

B

decreases with time

C

independent of time

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
`sqrt(x)=t+2impliesx=(t+2)^(2)`
`v=(dx)/(dt)=2(t+2)`
As `t` increases, `v` increases.
