MHT CET · Physics · Magnetic Effects of Current
If the distance between two current carrying parallel wire is made \(\left(\frac{1}{3}\right)^{r d}\) then the magnitude of the force between them (the same current is passing through both wires)
- A is tripled.
- B becomes 6 times.
- C becomes q times.
- D remains same.
Answer & Solution
Correct Answer
(A) is tripled.
Step-by-step Solution
Detailed explanation
Force between wires is inversely proportional to the separation between them,
\(F \propto \frac{1}{d}\)
Therefore, if the separation between wires becomes \(\left(\frac{1}{3}\right)^{r d}\), the magnitude of force is tripled.
\(F \propto \frac{1}{d}\)
Therefore, if the separation between wires becomes \(\left(\frac{1}{3}\right)^{r d}\), the magnitude of force is tripled.
