Consider a \(72\, cm\) long wire \(AB\) as shown in the figure. The galvanometer jockey is placed at \(P\) on \(A B\) at a distance \(x cm\) from \(A\). The galvanometer shows zero deflection. The value of \(x,\) to the nearest integer, is ..... \(cm\)
- A \(40\)
- B \(64\)
- C \(48\)
- D \(24\)
Answer & Solution
Correct Answer
(C) \(48\)
Step-by-step Solution
Detailed explanation
