2. Normal Reaction Force
3. Force of tension in a string
4. Gravitational force.
5. Electrostatic Force.
6. Magnetic Force

Classify them as contact and non contact forces and give one example.

Answer 1

1. Frictional Force
2. Normal Reaction Force
3. Force of tension in a string they are contact force
and 4. Gravitational force.
5. Electrostatic Force.
6. Magnetic Force are non- contact force

Answer 2

gravitational force .. magnetic force.. electrostatic force.. are non contact force frictional force ..normal reaction force.. and force of tensing is a string are contact force
