TS EAMCET · Physics · Magnetic Effects of Current
Three long, straight, parallel wires carrying different currents are arranged as shown in the diagram. In the given arrangement, let the net force per unit length on the wire ' \(C\) ' be \(\vec{F}\). If the wire ' \(B\) ' is removed without disturbing the other two wires, then the force per unit length on wire ' \(\mathrm{A}\) ' is
- A \(-\overrightarrow{\mathrm{F}}\)
- B \(3 \overrightarrow{\mathrm{F}}\)
- C \(2 \overrightarrow{\mathrm{F}}\)
- D \(-3 \overrightarrow{\mathrm{F}}\)
Answer & Solution
Correct Answer
(D) \(-3 \overrightarrow{\mathrm{F}}\)
Step-by-step Solution
Detailed explanation
Force on one wire. due to the other current carrying wive is \(\quad F=\frac{\mu_0^2 i_1 i_2 \times e}{4 \pi x}\) Given \(\left(\frac{F}{l}\right)_c=\vec{F}\)…
