A vector is located in the x-y plane. The x and y components of this vector are 4.00 m and 3.00 m, respectively. Find the angle that this vector makes with the positive y-axis.

Step-by-step explanation:

Consider vector A as shown in the figure given. The x- and y-component of vectors are given as Ax and Ay.

The angle of the vector with positive x-axis is given by,

∅ = ()

= ()

=

Where: Ax = x-component of the vector ann Ay=x-component of the vector

Thus, the angle of vector:

α = 90-∅

=

2nd one in the first row is correct
