Given that,
Horizontal force, F = 600 N
A mover pushes a dresser 9 meters across a bedroom.
To find,
The work done by the mover.
Solution,
The work done by an object is given by :
W = Fd
Where d is distance
W = 600 N × 9 m
= 5400 J
So, the work done by the mover is 5400 J.

Explanation:
Explanation:
In brief, electrons are negative charges and protons are positive charges. An electron is considered the smallest quantity of negative charge and a proton the smallest quantity of positive charge.
Two negative charges repel. Also, two positive charges repel. A positive charge and a negative charge attract each other (all experimentally verified.)
Point Charge: An accumulation of electric charges at a point (a tiny volume in space) is called a point charge.
Note: When an atom loses an electron, the separated electron forms a negative charge, but the remaining that contains one less electron or consequently one more proton becomes a positive charge. A positive charge is not necessarily a single proton. In most cases, a positive charge is an atom that has lost one or more electron(s).
