Answer:
False.
Explanation:
Yes the magnitude of a vector is always positive , but a vector consists of
- magnitude
- direction
when two vectors are added their direction may be opposite to each other For example-
,
then their resultant
This resultant vector's x and y component equal to y and x component of vector b so its magnitude will be equal to magnitude of vector b.
Therefore, the resultant magnitude not necessary equal to the magnitude of either vector.
