Question

Which mathematical equation correctly represents the Commutative Law of vector addition for two vectors \[\vec{P}\] and \[\vec{Q}\]?

पर्याय

• \[\vec{P} + \vec{Q} + \vec{R} = 0\]

• \[\vec{P} - \vec{Q} = \vec{Q} - \vec{P}\]

• \[\vec{P} + \vec{Q} = \vec{Q} + \vec{P}\]

• \[(\vec{P} + \vec{Q}) + \vec{R} = \vec{P} + (\vec{Q} + \vec{R})\]

Answer 1

\[\vec{P} + \vec{Q} = \vec{Q} + \vec{P}\]

Explanation:

The Commutative Law states that the order in which two vectors are added does not change the final resultant vector.
