1.	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 isA. 0.056 VB. 0.046 VC. 0.026 VD. 0.016 V
Answer» Correct Answer - D Induced emf, `e=\|(-NBA(costheta_(2)-costheta_(1)))/(Deltat)\|` `=\|-(800xx4xx10^(-5)xx0.05(cos90^(@)-cos0^(@)))/(0.1)\|=0.016V`
