Find the linear speed the bicycle required to power its head light by a generator, whose rubber shaft presses against the wheel of cycle of radius `0.33 m`, turns at an angular speed of `44` times as great as the angular speed of the tire itself. The coil consists of `75` turns, has an area of `2.6 xx 10^(-3) m^(2)`, and rotates in a `0.10 T` magnetic field. When the peak emf being generated is `6.0 V`.

Options

A. 2.5 m/s
B. 5 m/s
C. 2.3 m/s
D. 4.6 m/s

Answer

C

Explanation

`v=r(1/(44)omega_("coil") "Where" omega_("coil")=(e.m.f)/(NAB)`
