2. Electrostatic forces

3. Muscular force

4. Magnetic forces

• B. 1 and 3
• C. 1, 2 and 4
• D. All of the above

Answer 1

The correct option is C

1, 2 and 4

Gravitation, electrostatic force, and magnetic force are the non-contact forces because they work in both the cases, i.e. when they are in contact with an object and also when they are not in contact with an object. Muscular force works only when it is in contact with the object.
