A particle of mass 13 kg is on a rough plane inclined at an angle of θ to the horizontal, where tan θ = 5/12. The coefficient of friction between the particle and the plane is 0.3. A force of magnitude T N, acting parallel to a line of greatest slope, moves the particle a distance of 2.5 m up the plane at a constant speed. Find the work done by this force.
