Question

When a 20N force acts in two different ways to
displace a trolley in the same displacement. Find
the ratio of the work done as determined in both
the cases.
​

Answer 1

Answer:

work done = force × displacement

w/w=20×s/20×s=1(force is same and displacement is also same.)work done is a scale wuantity,it does not.matter in which direction u apply a force.
