1.

In the above problem. The plane of the coil is initially kept parallel to B. The coil is rotated by an angle theta about the diameter perpendicular to B and charge of amount Q flows through it. Choose the correct alternatives.

Answer»

(a) `THETA = 90^(@), Q = (Ban//R)`
(b) `theta = 180^(@), Q = (Ban//R)`
( c) `theta = 180^(@), Q = 0`
( d) `theta = 360^(@), Q = 0`

SOLUTION :(a,b,d):
Charge flowing in thecircuit `= (Deltaphi)/(R )`
where, `Deltaphi` = CHANGE in flux
`= phi_(final) - phi_(initial)`
and`R` = RESISTANCE in the circuit
