If the distance between two current carrying parallel wire is made ( 1 3 )^ r d then the magnitude of the force between them (the same current is passing through both wires)

Options

  1. Ais tripled.
  2. Bbecomes 6 times.
  3. Cbecomes q times.
  4. Dremains same.

Correct answer

A. is tripled.

Step-by-step solution

Force between wires is inversely proportional to the separation between them, F 1 d Therefore, if the separation between wires becomes ( 1 3 )^ r d , the magnitude of force is tripled.
