Question

OA is a rough surface whose equation is y = x2
[Here x-axis is horizontal and y-axis is vertical). A small
block of mass m is slowly pulled along the surface by
an external agent from position O (, 0) to position
A (a, a). If coefficient of friction is u, the work done against
the force of friction is
B
