Question

Which of the following two statements is more appropriate?
(a) Two forces are added using triangle rule because force is a vector quantity.
(b) Force is a vector quantity because two forces are added using triangle rule.

Answer 1

Answer:

The answer is (a).

Explanation:

This is because we know that force is a vector quantity and only vectors are added using triangle rule.

Answer 2

The most appropriate statement is (b), which states that because of using triangle rule, two forces are added, force is a vector quantity.

Explanation:

• Using triangle rule, two forces are added because one of the vector quantities is the force.
• We can say that this statement is appropriate because we can add only the vectors using triangle rule.  
• It is to be understood that force is the vector quantity has both direction and magnitude. In order to explain the force on an object, it should be understood that both the direction and the magnitude should be explained.

Therefore the correct answer is Option(b) Force is a vector quantity because two forces are added using triangle rule
