Q. A cube has sides of length = 0.320 . It is placed with one corner at the origin. The electric field is not uniform but is given by -4.95 2.17 .Find the electric flux through each of the six cube faces.
Q. A circular-shaped object of mass 10 kg has an inner radius of 7 cm and an outer radius of 24 cm. Three forces (acting perpendicular to the axis of rotation) of magnitudes 11 N, 25 N, and 13 N act on the object. The force of magnitude 25 N acts 28 below the horizontal. Find the magnitude of the net torque on the wheel about the axle through the center of the object.
