MHT CET 2022 Physics question
If the distance between two current carrying parallel wires is made rd then the magnitude of the force between them (same current is passing through both wires)
Answer: (A)
Solution
The force per unit length between two long parallel current-carrying wires is , so for fixed currents. If the distance becomes , then
