A conducting loop of radius R is present in a uniform magnetic field B perpendicular the plane of the ring. If radius R varies as a function of time `t', as R = R0 + t. The e.m.f induced in the loop is

a)2p (R0 + t) B clockwise
b)p(R0 + t)B clockwise
c)2p(R0 + t)B anticlockwise
d)zero
Correct answer is option 'C'. Can you explain this answer?

ε=− dϕ​/dt
=−β(dA/dt)
​⇒∣ε∣=βπd(R0​+t)2
=2πβ(R0​+t)
Since inward flux is increasing the EMF will be induced counter clockwise.
