Question

Two vectors A and B with magnitude 10 units each acting at a point making an angles 300

and 600 with X-axis

respectively.Find their resultant.​

Answer 1

Answer:

10$\sqrt{3}$

Explanation:

Magnitude of each vector = 10

Angle of A with x axis = 30 degree

Angle of B with x axis = 60 degree

Angle between A & B = 60 - 30 = 30 degree

resultant vector (R) = $\sqrt{A^{2} + B^{2} + 2ABcos30 }$

                                = $\sqrt{100 + 100 + 200 * 1/2}$

                           R   = $10\sqrt{3}$
