alleryWhich pair consists entirely of contact forces?
AGravitational force and electrostatic force
BWeight and gravitational force
CTension in a string and frictional force
DElectrostatic force and normal force
Answer & Solution
Correct answer: C. Tension in a string and frictional force
Tension and friction both arise through contact or attachment and are therefore contact forces.
Gravitational and electrostatic forces are field forces, and weight is also gravitational in origin.
