Question

A particle of mass M moves along a horizontal x axis from x=0 to x = L. The coefficient of kinetic friction varies as a function of x as p(x) = p,— ox, where p,, a are constants of appropriate dimensions, so that r{L)=0. The total work done by the frictional force during the motion is npMgl, where g is the acceleration due to gravity. The value of n is :
