Question

_______force is a non-contact force whereas _______ force is a contact force.

• A. Magnetic, frictional
• B. Muscular, gravitational
• C. Frictional, muscular
• D. Gravitational, magnetic

Answer 1

The correct option is A Magnetic, frictional

We know that,
A non-contact force is a force which can acts on an object without coming physically in contact with it.
Examples of non-contact forces are:
1. Gravitational force
2. Magnetic force
3. Electrostatic force

A force which is exerted by an object on another object only through physical touching is called a contact force.
Examples of contact forces are:
1. Muscular force
2. Frictional force

Thus, magnetic force is a non-contact force whereas frictional force is a contact force.
