Question

Two long straight wires **P** and **Q** carrying equal currents of **$$10 \, 	ext{A}$$** each were kept parallel to each other at a distance of **$$5 \, 	ext{cm}$$**. The magnitude of the magnetic force experienced by a **$$10 \, 	ext{cm}$$** length of wire **P** is **$$F_1$$**. If the distance between the wires is halved and the currents in them are doubled, the force **$$F_2$$** on a **$$10 \, 	ext{cm}$$** length of wire **P** will be:

Accepted Answer

A. $$8F_1$$

Answer

B. $$10F_1$$

Answer

C. $$\frac{F_1}{8}$$

Answer
