Q)

Calculate work done to move a body of mass 10 kg along an incline $(\theta=30^{\circ})$ with constant velocity through a distance 10 m $(g=10 m/s^2)$

\[(a)\;1000 \;J \quad (b)\;500 \;J\quad (c)\;250\;J \quad (d)\;10\; J\]

Sir,but the total force on body will be zero and even the velocity is constant. So how could be work done a\c work enegy theorem?
