Answer:
The net force is 20N in the direction of the 80N force.
Explanation:
The net force is the resultant force acting on a body. This force is that singular force that will have the same magnitude and effect as the network of forces on a body.
In this problem:
Force 1 = 80N
Force 2 = 60N
Net force = Force 1 - Force 2
Net force = 80N - 60N
Net force = 20N
The net force is 20N in the direction of the 80N force.

The measure of the force of gravity on an object, expressed as mass of the object times acceleration due to gravity is called
weight
As the plastic sphere is charged, therefore it experience an electric force when placed in an electric fields and also experiences gravitational force acts downward so the electric force must act upward.
Let is electric force and is gravitational force.
If these forces are balanced, therefore
or
Given, and .
Substituting these values in above equation we get,
Thus, the magnitude of electric field is .
As the charge is negative, the electric field at the location of the plastic sphere must be pointing downward.
