A) \[48\text{ }V\]
B) \[4.8\text{ }V\]
C) \[4.8\times {{10}^{-1}}\,V\]
D) \[4.8\times {{10}^{-2}}\,V\]
Correct Answer: D
Solution :
From Faradays . law of electromagnetic induction, the emf induced is given by \[e=-M\frac{di}{dt}\] ...(i) where M is coefficient of mutual inductance, \[\frac{di}{dt}\]is rate of change of current. Also, mutual inductance of two coaxial solenoids is given by \[M=\frac{{{\mu }_{0}}{{N}_{1}}{{N}_{2}}A}{l}\] ??(ii)You need to login to perform this action.
