The coefficient of static friction between a block of mass m and an incline is `mu_s=03`, (a). What can be the maximum angle `theta` of the incline with the horizontal so that the block does not slip on the plane? (b). If the incline makes an angle `theta/2` with the horizontal, find the frictional force on the block.
