Plz help:) The answer is (B) Why did (C) was not chosen?

OpenStudy (maheshmeghwal9):

OpenStudy (maheshmeghwal9):

A vector question!

OpenStudy (anonymous):

is it multiple choice question

OpenStudy (anonymous):

in this the most suitable answer for the question is correct

OpenStudy (maheshmeghwal9):

ya it is MCQ

OpenStudy (maheshmeghwal9):

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.

OpenStudy (anonymous):

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.

OpenStudy (anonymous):

k i understand

OpenStudy (anonymous):

its all about directions

OpenStudy (maheshmeghwal9):

Thax I got it:)
