A coil of surface area \(200 cm^2\) having 25 turns is held perpendicular to the magnetic field of intensity \(0.02 \frac{Wb}{ m ^2}\). The resistance of the coil is \(1 \Omega\). If it is removed from the magnetic field in 1 s , the induced charge in the coil is ________ C.
- A 0.1
- B 1.0
- C 0.01
- D 0.001
Answer & Solution
Correct Answer
(C) 0.01
Step-by-step Solution
Detailed explanation
C
charge \(Q =\frac{\Delta \phi}{ R }\)
\(Q=\frac{N_B A}{R}\)
\(\begin{array}{c} Q = \ \frac{25 \times 0.02 \times 200 \times 10^{-4}}{1}\end{array}\)
\(Q =0.01 C\)
charge \(Q =\frac{\Delta \phi}{ R }\)
\(Q=\frac{N_B A}{R}\)
\(\begin{array}{c} Q = \ \frac{25 \times 0.02 \times 200 \times 10^{-4}}{1}\end{array}\)
\(Q =0.01 C\)
