Which of the following is a field force rather than a contact force?
AFriction between two surfaces
BTension in a stretched string
CElectrostatic force between two charges
DNormal force exerted by a table
Answer & Solution
Correct answer: C. Electrostatic force between two charges
Electrostatic force acts without physical contact, so it is a field (range) force. Friction, tension, and normal force all require contact or attachment between bodies.
