A snake of mass M and length L is lying on an incline of inclination `30^(@)`. It craws up slowly and overhangs half its length vertically. Assume that the mass is distributed uniformly along the length of the snake and its hanging part as well as the part on the incline both remain straight.

(a) Find the work done by the snake against gravity (Wg) (b) Will the answer to part (a) be different if the snake were of half the length but of same mass.
