Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When distance increases, electrostatic force ____ ; we call this relationship ____ proportional
A
decreases;directly
B
decreases;inversely
C
increases;inversely
D
increases;directly
Explanation: 

Detailed explanation-1: -Inverse relationships are common in nature. In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects.

Detailed explanation-2: -The magnitude of the electrostatic force F between two point charges q1 and q2 is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them.

Detailed explanation-3: -The size of the force varies inversely as the square of the distance between the two charges. Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value.

Detailed explanation-4: -Electric forces are inversely proportional to the square of the distance from the source of the force.

Detailed explanation-5: -The law says that the force is proportional to the amount of charge on each object and inversely proportional to the square of the distance between the objects.
