Question

A=i+j What is the angle between the vector and x-axis?

Answer 1

Answer: 45°

Explanation:

A = i + j

Magnitude of vertical component along y-axis = Magnitude of horizontal component along x-axis

Tanθ = Vertical component / Horizontal component

Tanθ = 1

θ = 45

Answer 2

Answer:

45°

Explanation:

since, A = i+j

that implies,

$\tan - 1(y \div x) = \tan - 1(1 \div 1) = 45$
