Electromagnetic Induction question

2023 · 10 Apr · Shift 2 · Q60

JEE MainPhysicsElectromagnetic InductionNumerical+4 / −1
A square loop of side 2.0 cm2.0 \mathrm{~cm}2.0 cm is placed inside a long solenoid that has 50 turns per centimetre and carries a sinusoidally varying current of amplitude 2.5 A2.5 \mathrm{~A}2.5 A and angular frequency 700 rad s−1700 ~\mathrm{rad} ~\mathrm{s}^{-1}700 rad s−1. The central axes of the loop and solenoid coincide. The amplitude of the emf induced in the loop is x×10−4 Vx \times 10^{-4} \mathrm{~V}x×10−4 V. The value of xxx is ‾\underline{\hspace{2cm}}​.  (Take, π=227 ) \text { (Take, } \pi=\frac{22}{7} \text { ) } (Take, π=722​ )
