The diagram given below shows a solenoid carrying time varying current `l= l_(0)t`. On the axis of the solenoid, a ring has been placed. The mutual inductance of the ring and the solenoid is M and the self inductance of the ring is L. If the resistance of the ring is R then maximum current which can flow through the ring is

Options

A. `((2M+L)l_(0))/(R )`
B. `(Ml_(0))/(R )`
C. `((2M-L)l_(0))/(R )`
D. `((M+L)I_(0))/(R )`

Answer

C
