Physics · Vectors
The magnitudes of vectors Vector(OA), Vector(OB), and Vector(OC) are all equal to R. Vector(OA) is along the positive x-axis, Vector(OB) makes an angle of 45° with the positive x-axis in the first quadrant, and Vector(OC) makes an angle of 45° with the negative x-axis in the second quadrant. The direction of Vector(OA) + Vector(OB) - Vector(OC) with the positive x-axis will be given by:
- 1tan-1(1)
- 2tan-1(√3 - 1 + √21 - √3 + √2)
- 3tan-1(11 + √2)✓
- 4tan-1(√3 - 1 + √21 + √3 - √2)
Correct answer
tan-1(11 + √2)
