The deflection in moving coil galvanometer falls from \(25\) divisions to \(5\) division when a shunt of \(24\ \Omega\) is applied. The resistance of galvanometer coil will be :
- A \(12\ \Omega\)
- B \(96\ \Omega\)
- C \(48\ \Omega\)
- D \(100 \ \Omega\)
Answer & Solution
Correct Answer
(B) \(96\ \Omega\)
Step-by-step Solution
Detailed explanation
Let \(\mathrm{x}=\) current/division Now \(5 \mathrm{x} \times \mathrm{G}=20 \mathrm{x} \times 24\) \( \mathrm{G}=4 \times 24 \) \( \mathrm{G}=96 \ \Omega\)

- In an experiment to determine the Young's modulus, steel wires of five different lengths \((1,2,3,4\) and \(5\,m )\) but of same cross section \(\left(2\,mm ^{2}\right)\) were taken and curves between extension and load were obtained. The slope (extension/load) of the curves were plotted with the wire length and the following graph is obtained. If the Young's modulus of given steel wires is \(x \times 10^{11}\,Nm ^{-2}\), then the value of \(x\) is
