Questions  

The electric potential in a region is given by the relation V(x)=4+5x2. If a dipole is placed at position (-1,0) with dipole moment 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 and it is in anticlockwise direction

detailed solution

Correct option is A

V(x)=4+5x2 .E→=-dvdxi^=-10x i^Net force will be zero and torque not zero and rotation will be along clockwise direction.
