Question
The electric potential in a region is by the relation V(x) = 4 + 5x2. If a dipole is placed at position (-1, 0) with dipole moment 
pointing along positive Y-direction, then
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 and it is in anticlockwise direction
Solution
V(x) = 4 + 5x2 ⇒
= 10xî∴ Net force will be zero and torque not zero and rotation will be along clockwise direction
