APQ is a rough surface The portion AP is parabolic given by equation x 16y The point A assumed to be origin The portion PQ is a straight line of length 20 3 m the coefficient of friction between block and 1 A block of mass 3 kg 3 is moved on surface APQ by applying a force on it The direction of force is always tangential to the surface APQ The line PQ is tangent on the curve AP at P If the block moves very slowly on the surface then find the work done by applying force in joule surface APQ is A 12 m
