A 100 turns coil of area of cross-section 200 `"cm"^(2)` having `2 Omega` resistance is held perpendicular to a magnetic field of 0.1 T. If it is removed from the magnetic field in one second, the induced charge produced in it is

Options

A. 0.2 C
B. 2 C
C. 0.1 C
D. 1 C

Answer

C

Explanation

Here, `q= | ( d phi)/( R) | = (phi_("max") )/( R) = ("BAN")/("R")`
Now, `q = (0.1 xx 200 xx 10^(-4) xx 100)/( 2)`
`q= 0.1`C
