What happens if a vector is multiplied by a number

Question

What happens if a vector is multiplied by a number – 2?

Options:

A . The magnitude of the vector is doubled but its direction remains the same

B . The magnitude of the vector remains the same but its direction is reversed

C . The magnitude of the vector is doubled and its direction is reversed

D . Neither the magnitude nor the direction of the vector undergo any change

Answer: Option C
:
C
Multiplication of a vector by a real negative number – n makes its magnitude n times and also reverses thedirection of the vector.
Hence the correct choice is (c).
