Hi friend
---------------
Your answer
-------------------
Weight of the book = 5 N
The book is moved from the ground to three different heights.
Now,
----------
Mass = m
Acceleration due to gravity = g
mg = 5 N (given)
Height = Either 1 m or 1.5 m or 2 m
Potential energy formula = m × g × h
Potential energy when the book is raised to a height of 1 m.
h = 1 m
Ep = (5 × 1) Joules = 5 J
When,
----------
The stone is moved to a height of 1.5 m.
Ep = ( 5 × 1.5) Joules = 7.5 J
Again,
-----------
When the stone is moved to a height of 2 m.
Ep = (5 × 2) Joules = 10 J

Potential energy =mgh
1
h=1m,mg=5N similarly
mgh=1 *5=5 joule
2
h=1.5, pe=mgh=5*1.5=7.5joule
3
h=2m,pe =mgh =5*2=10
Total=22.5 joule
