Explanation:
<u>Gravitational Potential Energy</u>
It's the capacity of an object to do work due to its relative height from a fixed reference point.
It's computed as
GPE=m.g.h
Where m is the mass of the object, h is its height and g is the acceleration of gravity,
The mass of water is given as
The height above the rocks is h=50 m. Let's compute the GPE
It should be expressed in scientific notation
The GPE at the bottom, where h=0
The change of gravitational potential energy is:
By definition, the electric force is given by:
Where,
q1: electric charge of object number 1.
q2: electric charge of object number 2.
d: distance between both objects
k: proportionality constant
Therefore, the magnitude of the electric force is affected by:
1) The product of the charges of the objects
2) The distance between objects
Answer:
The factors that affect strength of the electric force between two objects are:
1) The product of the charges of the objects
2) The distance between objects
