Question

if two vectors are equal in magnitude, are they necessarily equal? multiple choice yes. since vectors are scalar quantities, if two vectors have the same magnitude, they are equivalent. no, only if they share the same origin (begin at the same point). no; for vectors to be equal, they must also have the same direction. no, only if they end at the same point.

Explanation:

Vectors are defined by both magnitude and direction. Equal vectors need same magnitude AND direction. The first option is wrong (vectors are not scalars). Origin or endpoint don't determine vector equality, so the other wrong options are eliminated.

Answer:

C. No; for vectors to be equal, they must also have the same direction.
