Question

1 multiple choice 2 points which fundamental force is primarily responsible for the attraction between protons and electrons? strong weak gravitational electromagnetic 2 multiple choice 2 points which force is responsible for producing a stable nucleus by opposing the electrostatic force of repulsion between protons? strong weak frictional gravitational

Explanation:

1. Protons are positively charged and electrons are negatively charged. The electromagnetic force acts between charged particles. Opposite charges attract each other due to the electromagnetic force.
2. The strong nuclear force acts over a very short range. It holds protons and neutrons together in the nucleus. Protons repel each other due to electrostatic (electromagnetic) repulsion (like charges repel). The strong force overcomes this repulsion to keep the nucleus stable.

Answer:

1. D. electromagnetic
2. A. strong
