Given that

\mathrm{\vec A} + \mathrm{\vec B} + \mathrm{\vec C} = 0

. Out of three vectors, two are equal in magnitude and the magnitude of third vector is 

\sqrt 2

times that of either of the two having equal magnitude. Then the angles between vectors are given by

View answer and explanation

Correct option: B

90^\circ ,135^\circ ,135^\circ

Option B (

90^\circ ,135^\circ ,135^\circ

) is correct because it satisfies the condition that the sum of the three vectors is zero, with two vectors equal in magnitude and the third being

\sqrt{2}

times the magnitude of the others.
