Question

The resultant of two vectors A and B is C = 2.2 i + 3.4 j. If A = 1.5 i - 2.0 j, find magnitude and angle of B.
Options
A 29.7 unit, 82.6°
B 29.7 unit, 7.4°
C 2.45 unit, 82.6°
D 5.45 unit, 82.6°
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

B = C - A, then magnitude = √(Bx² + By²), angle = arctan(By/Bx).

Hint

Use vector subtraction and Pythagoras.
