A moving coil galvanometer has 10 turns each of length 12 cm and breadth 8 cm the coil of MCG carries a current of 125 `mu` A The coil is kept perpendicular to uniform magnetic field of induction `10^(-2)` T the twis t constant of phosphor bronz fibre is `12xx10^(-9)` Nm/degree calculate the defection produced

Options

A. `10^(@)`
B. `20^(@)`
C. `30^(@)`
D. `60^(@)`

Explanation

To solve the problem step by step, we will use the formula for the deflection (θ) produced in a moving coil galvanometer:

\[ \theta = \frac{N \cdot B \cdot A \cdot I}{C} \]

Where:
- \(N\) = number of turns in the coil
