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

Options

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

Answer

A, C

Explanation

`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
