JEE Main 2023 — Alternating Current Question with Solution

A square shaped coil of area $$70{\mathrm{cm}}^2$$ having 600 turns rotates in a magnetic field of $$0.4{\mathrm{wbm}}^{-2}$$, about an axis which is parallel to one of the side of the coil and perpendicular to the direction of field. If the coil completes 500 revolution in a minute, the instantaneous emf when the plane of the coil is inclined at $$60^{\circ }$$ with the field, will be ____________ V. (Take $$\pi =\frac{22}{7}$$)
