Answer 2

Answer:

The correct answer to the question -"A circular loop carrying current I in anti-clockwise direction is situated near a long straight wire carrying current io. Both are in the same plane as shown in figure. The loop will :" is-

(c) Moves away from the wire

Explanation:

The Correct option is C)

Suppose current is flowing from conductor A to D.

Then the side AB and the  long straight wire carries  current in the same direction,

therefore, will attract each other.

The side CD carry current in the opposite direction, and the long straight wire

therefore,  will repel each other.

On side DA, the force  will be equal and opposite to force  on side BC .

Since CD  and  AB are farther from each other ,  the force of attraction  will exceed the force of repulsion ,

that is,   AB  will exceed the force of repulsion on CD.

Therefore, the net force of attraction on the loop ABCD and it will move towards the wire.

so, the correct option is, (c) moves away from the wire.
