A coil has an area of `0.05 m^(2)` and it has `800` turns. It is placed perpendicular in a magnitude field of strength `4xx10^(-5)Wb//m^(2)`, it is rotated through `90^(@)` in `0.1` sec. the average e.m.f. induced in the coil is

A

0.056 V

B

0.046 V

C

0.026 V

D

0.016 V

Text Solution

Verified by Experts

The correct Answer is:
D
`|e|=(NDeltavarphi)/(Deltat)=(800xx4xx10^(-5)xx0.05)/0.1=0.016V`.
