Question

Two long and parallel straight wires A and B carrying currents of 8*0A and 5*0A in the same direction are separated by a distance of 4*0cm. Estimate the force on a 10cm section of wire A.

Answer 1

Answer:

2×10^-5

Explanation:

as force per unit length = u°/4π × 2I(1)I(2) / d

therefore putting the values and multiplying the equation by 10 cm we get the answer
