The position vector of a particle is `vecr=4t^(2)hati+2thatj+3thatk`. The acceleration of a particle is having only

A

X-component

B

Y-component

C

Z-component

D

X-Y component

Text Solution

Verified by Experts

The correct Answer is:
C
`vecr=4t^(2)hati+2thatj+3hatk,vecv=(dvecr)/(dt)=8thati+2hatj`
`a=(d^(2)r)/(dt^(2))=8hatia` is having only X-component.
