A child lifts a book of mass 1kg from the table to a cupboard at a height 2m from the floor .find the potential energy with respect to floor

By given information we know that height upto which the book is lifted is 2 m from grouund.
We know,

Gravitational potential energy = work done against gravity = mgh
Where,
m- mass of book
g - gravity
h - height
Thus,
P.E. = 1 × 9.8 × 2 =19.6 J

Thus, potential energy of book at height of two metres w.r.t floor is 19.6 J
