Answer & Solution

Correct Answer

(C) \(5\)

Step-by-step Solution

Detailed explanation

It should be mentioned, \(10 \; cm\) wire is part of long wire. Force experienced by unit length of wire \(=\frac{\mu_{0} I _{1} I _{2}}{2 \pi d }, I _{1}= I _{2}=5 \; A\) Force experienced by wires of length \(10 \; cm\)…
