Question

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

• A. Shape of the object on which the force is acting
• B. Direction in which the force is acting
• C. Size of the object on which the force is acting
• D. Magnitude of the force

Answer 1

Answer: (B), (D)

The correct options are
B

Direction in which the force is acting

D

Magnitude of the force

Force is a physical quantity which has both magnitude as well as direction. If there are two forces of the same magnitude and one of them is acting towards east while the other is acting towards west, their effect will be different. Thus, to define a force accurately, both magnitude and direction are required. The force is not defined by the shape and size of the object on which it is acting.
