What should be the minimum coefficient of static friction between an inclined plane and the solid cylinder, for which the cylinder does not slip on the inclined plane?

Are there numerical in physics class 11?

The area of cross-section of cylindrical wire increases uniformly from left to right as shown in figure. When steady current flows in the wire, then in the direction of current

The current in a coil changes from 8 A to zero in 0.2 s. If self-inductance is 4 H then average induced emf is:
