Problem

A loop of area

1 \text{ m}^2

is placed in a magnetic field

B = 2 \text{ T}

, such that plane of the loop is parallel to the magnetic field. If the loop is rotated by

180^\circ

, the amount of net charge passing through any point of loop, if its resistance is

10 \Omega

, is (a)

0.4 \text{ C}

(b)

0.2 \text{ C}

(c)

0.8 \text{ C}

(d)

0 \text{ C}
