i wanna know why did not he chose 'C'?
OpenStudy (anonymous):
well both are correct if we look in vectors but more suitable was b) as it explains both rules B) and C)
OpenStudy (anonymous):
options not rules
OpenStudy (anonymous):
and above i meant the question have more than one answer
OpenStudy (ujjwal):
Its b.
That options seems to be correct logically.
Example:
Let \(\vec{A}=6m/s\) and \(\vec{B}=5m/s\) and they act at an angle of \(180^0\). So, \(\vec{C}=\vec{A}+\vec{B}=1m/s\) along direction of \(\vec{A}\) here \(C<A\) and \(C<B\).
So, b is the answer.

well c) is a rule in vectors.
OpenStudy (ujjwal):
Talking about option c. And in my above example you can also see \(C\neq A+B\) see their magnitudes.
