A cycle wheel with 10 spoken was moved at a certain speed in a plane normal to the earth's magnetic induction. It was found that an emf of `40 mu v` was induced across each spoke (i.e. Between the axis and the rim of the cycle wheel). What is the total emf induced across the ten spoken?

Options

A. `400 mu v`
B. `200 mu v`
C. `40 mu v`
D. `4 mu v`

Answer

C

Explanation

All the spokes have the same common ends (i.e. the axle and the rim of the wheel). Hence they are connected in parallel.
`:.` The emf induced between the ends of a single spoke or 10 spoke is the same i.e. `40 mu v`.
