Question

Two long parallel wires are separated by a distance 8 cm carry electric currents of 3 ampere and 5 ampere is the distance of null point from the conductor carrying larger current when currents are grlowing in the same direction is

Answer 1

Answer:

 5 cm from 5 ampere current carrying wire.

Explanation:

For null point net magnetic field will be zero shown in the attachment.

Apply magnetic field formula for current carrying wire.

Take,  I1 = 5 A

           I2 = 3 A

AND SOLVE AS GIVEN BELOW.
