Question

Find out the value of resultant vector of two vectors when the angle between two vectors are
0°, 30°,45°,60º,120°,180°
respectively.
​

Answer 1

Explanation:

We know, Value of resultant vector= √A2 + B2 + 2AB Cos theta

Where A and B are two vectors and theta is the angle between them.

So value of resultant vector when the angle between two vectors A and B is:

0°- √ A2+ B2 + 2AB

30°- √ A2+ B2 + √3AB

45° - √A2+ B2 + √2AB

60° - √A2+ B2+ AB

120° -√A2 + B2 -AB

180° - √A2 + B2- 2AB
