The magnitude of non-contact force depends upon:
The magnitude of non-contact force depends upon:
- A. Distance between two bodies
- B. Mass of the two bodies
- C. chemical properties of the two bodies
- D. All of the above
Step-by-step solution
Non-contact forces, such as gravitational and electrostatic forces, depend on the distance between the two bodies; for example, gravitational force follows an inverse square law. While gravitational force also depends on mass, not all non-contact forces depend on mass (e.g., electrostatic force depends on charge, not mass). Chemical properties are not a factor for fundamental non-contact forces. Therefore, only option A is universally correct.
