Solution
The correct options are A Work done by Ram and Hari is equal. C Energy spent by Ram and Hari is equal. Work is defined as the product of force and displacement. Since mass or in turn weight of the bag is same and the displacement is also same, so work done is same. Energy is defined as the capacity of doing work. So energy will be the same for both as work done is same. Energy has the same unit as work i.e Joule.
