If the angle between two non-zero vectors

\mathbf{A}

and

\mathbf{B}

120^{\circ}

, its resultant

C

will be

View answer and explanation

Correct option: C

C>|\mathbf{A}-\mathbf{B}|

Option C (

C>|\mathbf{A}-\mathbf{B}|

) is correct because when the angle is 120 degrees, the magnitude of the resultant vector is greater than the magnitude of the difference of the two vectors.
