Question

Given that `vecA+vecB+vecC=0`, out of three vectors two are equal in magnitude and the magnitude of third vector is `sqrt2` times that of either of two having equal magnitude. Then angle between vectors are given by
A. `30^(@),60^(@),90^(@)`
B. `45^(@),45^(@),90^(@)`
C. `90^(@),135^(@),45^(@)`
D. `90^(@),135^(@),135^(@)`

Answer 1

Correct Answer - D
(d) Angle between A and B Is `90^(@)`

Between B and C `135^(@)`and that betweeen A and C is `135^(@)`
