Magnitude And Directions Of A Vector

Currents of 10 A and 20 A are passed in two long parallel wires A and B, as shown in the figure. A wire C of 15 cm length is placed just in between these two wires, in which 5 A of current is passed. Then what will be the force acting on the wire C?

(i) Calculate the number of turns in the secondary coil.

(ii)Input power.

What is the magnitude of the current in the given circuit?
