Question

If F =(2i+2j)N. what is the angle that F makes with x-axis?
(a)30 degree
(b)45 degree
(c)60 degree
(d)90 degree
​

Answer 1

Answer:

The required angle is 45°.

Answer 2

we have to find the angle made by F with x - axis where F = (2i + 2j) N.

solution : let θ is the angle made by F with x - axis.

using formula, tanθ = y/x

where y = component of force along y - axis = 2

x = component of force along x - axis = 2

so, tanθ = 2/2 = 1 = tan45°

⇒θ = 45°

Therefore the angle made by F with x - axis is 45°
