Answer:
Work done by Ram = 8 Joule
Explanation:
According to the question
Force applied by Ram = 20N
Distance moved by boo(Displacement) = 40 cm = 0.4 m
Work Done = Force×Displacement
Work Done = 20 × 0.4
Work Done = 8 Joule
As the force and displacement is in same direction therefore work done is positive.
NOTE:
If force and displacement will be in opposite direction then workdone would have been negative.
