ONLY ONE OUT OF FOUR OPTIONS IS CORRECT
1. Vectors A, B, C lie in XY plane and their resultant is R. The magnitudes of A, B and R are 100, 200 and 200
respectively. The angles made by these vectors with the positive direction of X axis are 60º, 150º, and 90º
respectively. Therefore, the magnitude and the angle made by C with positive direction of X axis respectively
are
(a) 75, 315º (b) 110, 45º (c) 156, 240º (d) 124, 6.2º
Ans. [d]
Sol.
30º 60º
100 200
100
R(200)
