Which of the following sets contains one field force, one contact force, and one force due to attachment to another body, respectively?
AGravitational force, frictional force, spring force
BNormal force, electrostatic force, weight
CTension, frictional force, electrostatic force
DWeight, spring force, gravitational force
Answer & Solution
Correct answer: A. Gravitational force, frictional force, spring force
Field force: gravitational force acts at a distance. Contact force: frictional force requires surfaces in contact. Attachment force: spring force is listed separately under attachment to another body. The other options place the forces in the wrong categories.
