Question

Resultant of vectors A = 1.5i - 2.0j and C = 2.2i + 3.4j is C. Find vector B (magnitude and angle with x-axis).
Options
A B = 0.7i + 5.4j
Correct Answer
B B = 0.7i + 1.4j
C B = 3.7i + 1.4j
D B = 0.7i + 5.4j
Correct Answer

Option A is the correct answer.

Detailed Explanation

C = A + B → B = C - A = (2.2-1.5)i + (3.4+2)j = 0.7i + 5.4j.

Hint

Use vector subtraction: B = C - A.
