A circular coil of 500 turns encloses an area of `0.04 m^2`. A uniform magnetic field of induction `0.25 Wb'/'m^2` is applied perpendicular to the plane of the coil. The coil is rotated by 90° in 0.1 second at a constant angular velocity about one of its diameters. A galvanometer of resistance `25Omega` was connected in series with the the coil. The total charge that will pass through the galvanometer is -
