Question

2 multiple choice 1 point which of the following statements best describes the differences between the gravitational force and the electromagnetic force? the electromagnetic force is weaker than gravity and can be either attractive or repulsive, while gravity is only attractive the electromagnetic force is stronger than gravity and can only be repulsive, while gravity is only attractive the electromagnetic force is stronger than gravity and can be either attractive or repulsive, while gravity is only attractive the electromagnetic force is weaker than gravity and can only be attractive, while gravity can be either attractive or repulsive.

Explanation:

• The electromagnetic force is much stronger than the gravitational force. For example, in an atom, the electromagnetic force between electrons and protons is far greater than the gravitational force between them.
• The electromagnetic force can be attractive (e.g., between opposite charges: electron - proton) or repulsive (e.g., between like charges: electron - electron, proton - proton).
• Gravity is only attractive. It acts between any two objects with mass, and there is no such thing as "negative mass" that would make gravity repulsive in the same sense as electromagnetic charge - based repulsion.

Answer:

The electromagnetic force is stronger than gravity and can be either attractive or repulsive, while gravity is only attractive.
