gravitational force of earth is given by
so here the force will depend on the product of mass and gravity
so here force will be more if we took the condition of more masses
so here in 3rd figure
there will be maximum force of gravity on it
because it will have 6 boxes so there will be maximum mass
So figure of truck with 6 boxes on it is correct answer

Answer:
0 J
Explanation:
From the diagram below; we would notice that the Force (F) = Tension (T)
Also the angle θ adjacent to the perpendicular line = 90 °
The Workdone W = F. d
W = Fd cos θ
W = Fd cos 90°
W = Fd (0)
W = 0 J
Hence the force is perpendicular to the direction of displacement and the net work done in a circular motion in one complete revolution is = 0
