Question

Which of the following quantities are required to define a force?

• A. Area on which the force is being applied.
• B. Magnitude of the force being applied.
• C. Direction in which the force is being applied.
• D. Mass of the object on which the force is being applied.

Answer 1

Answer: (B), (C)

The correct options are
B Magnitude of the force being applied.
C Direction in which the force is being applied.

Force is a vector i.e. it has both magnitude and direction. Therefore the least requirement to define a force accurately is both magnitude and direction of the force.
