while many properties are similar, one important difference between electric and gravitational forces is that unlike gravity, electric charge:
a)can be transferred
b) objeys an inverse-square law
The correct answer is a) can be transferred.
To get the answer to this question, you need to compare the properties of electric and gravitational forces. Let's break it down:
Electric Force:
Electric charges can be positive or negative. Like charges repel each other, while opposite charges attract each other. One of the unique properties of electric charge is that it can be transferred. This means that charged particles can gain or lose charge by either gaining or losing electrons.
Gravitational Force:
Gravitational force is the force of attraction between objects with mass. It depends on the mass of the objects and the distance between them. Unlike electric charge, gravitational force does not involve the transfer of mass. Mass is a fundamental property of an object and cannot be gained or lost like electric charge.
Therefore, the important difference between electric and gravitational forces is that electric charge can be transferred, while gravity does not involve the transfer of mass. Hence, option a) "can be transferred" is the correct answer.
