Assertion:- If dipole `(vecP_(1))` is moved along the line normal to the axis (dotted line shown) of another dipole `(vecp_(2))`, their interaction energy does not chagne.

Reason:- Electric field of `vecp_(2)` at the position of `vecp_(1)` is normal to `vecp_(1)`.

A

If both Assertion `&` Reason are True `&` the Reason is a correct explanation of the Assertion.

B

If both Assertion `&` Reason are True but Reason is not a correct explanation of the Assertion.

C

If Assertion is True but the Reason is False.

D

If both Assertion `&` Reason are False.

Text Solution

Verified by Experts

The correct Answer is:
A
Position of `vecP_(1)` remains at equitorial position of `vecP_(2)` hence electric field of `vecP_(2)` at position of `vecP_(1)`
always remains perpendicular `vecU=-vecP.vecE=0`
