As per your syllabus, a vector in xy-plane can be written in component form as which expression?
AA = √(A_x A_y)
BA = A_x î + A_y ĵ
CA = A_x · A_y
DA = A_x î × A_y ĵ
Answer & Solution
Correct answer: B. A = A_x î + A_y ĵ
syllabus eqn 3.12: A = A_x î + A_y ĵ (sum of two perpendicular component vectors).
