Assertion : Current in wire-1 is in the ...

Assertion : Current in wire-1 is in the direction as shown in figure. The bottom wire is fixed. To keep the upper wire stationary, current in it should be in opposite direction.
Reason : Under the above condition, equilibrium of upper wire is stable.

A

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion

C

If Assertion is true, but the Reason is false.

D

If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B
To balance the wieght foce on upper wire should be upwrds (repulsion). Further equilibrium can be checked by displacig the wire from equilibrium position.
