Question

which of the following is/are true?
i. force is a scalar quantity.
ii. force is a vector quantity.
iii. a force is a push or a pull between objects that occurs only when the objects are in physical contact.
iv. non - contact forces are also called action - at - a - distance forces.
○ ii only
○ ii and iv only
○ i only
○ ii and iii only
○ i and iii only

Explanation:

Brief Explanations

Force has magnitude and direction, so it is a vector quantity, not a scalar (I is false, II is true). Forces can act at a distance (e.g., gravitational, electromagnetic forces), so III is false. Non - contact forces that act without physical contact are indeed called action - at - a - distance forces, so IV is true.

Answer:

B. II and IV only
