Which situation describes a non contact force acting on an object

Answer 1

A non contact force acting on an object can be described in various situations, such as:

1. Magnetic force: When a magnet attracts or repels another object without physically touching it, it is an example of a non-contact force. For instance, when two magnets are brought close to each other, they exert magnetic forces on each other without direct contact.

2. Electric force: Similarly, when two charged objects exert forces on each other without touching, it is an example of a non-contact force. For instance, positively charged and negatively charged objects can attract or repel each other without direct contact.

3. Gravitational force: The force of gravity is a non-contact force that acts between any two objects with mass. For example, the gravitational force between the Earth and an object on its surface keeps it grounded without physical contact.

In all these scenarios, the forces act without requiring objects to physically touch each other.
