GIVEN:-
cross sectional area = 0.05 m²
number of turns = 800
magnetic field through perpendicular to the coil B = 4 × 10^-5 Wb/m²
= 0.016 V

SOLUTION
Number of turns, n= 800
magnetic field, B= 4× 10^-5 Wb/m^2
Area, A= 0.05m^2
Initial flux= nBA
On rotating The coil by 90°, flux becomes zero.
Therefore,
e= dtheta/dt
=) e= nBA/dt
=)e= 800×4×10^-5× 0.05/0.1
=) e= 0.016 V
OPTION (d)✓
hope it helps ✔️
