The alectric potential in a region is given by the relation `V(x)=4+5x^(2)`. If a dipole is placed at position `(-1, 0)` with dipole moment `vec(p)` pointing along positive Y-direction, then

A

Net force on the dipole is zero.

B

Net torque on the dipole is zero

C

Net torque on the dipole is not zero and it is in clockwise direction

D

Net torque on the dipole is not zero it is in anticlockwise direction

Text Solution

Verified by Experts

The correct Answer is:
A, C
`V(x)=4+5x^(2)rArr vec(E)=-10xhat(i)`
`:.` Met force will be zero and torque not zero and rotation will be along clockwise direction
