We have two electric dipoles. Each dipole consists of two equal and opposite point charges at the ends of an insulating rod of length d. The dipoles sit along the x-axis a distance r aparts oriented as shown in fig. Their separation rgtgtd. The dipole on the left:

A

will feel a force to the left

B

will feel a force to the right

C

wiff feel a torque trying to make it rotate counterclockwise

D

will feel no torque

Text Solution

Verified by Experts

The correct Answer is:
A, D
`E_(1)` and `E_(2)` are the electric field due to dipole (1) so `E_(1)gtE_(2)`

Force on dipole (2) : `qE_(1)("left")+qE_(2)("right")=qE_(1)-E_(2))"left"`. Diole (2) will not experience any torque, because lines of action of both forces are same.
