A coil of area `A` lies in a uniform magnetic field `B` with its plane perpednicular to the field. In this position the normal to the coil makes an angle `0^(@)` with a field. The coil rotates at a uniform rate about its diameter to complete one rotation in time `T` . Find the average induced e.m.f. in the coil during the interval when coil rotates from:  (a) `0^(@)` to `90^(@)`  (b) `90^(@)` to `I80^(@)`  (c) `I80^(@)` to `270^(@)` (d) `270^(@)` to `360^(@)`
