Question

A vector is given A=i+j the angle made by the vector with x axis​

Answer 1

Answer:

where θ is the angle made by the vector with x axis. Hence, the angle (θ) made by the vector with the x-axis is 45°.

Explanation:

....

Answer 2

Answer:

The angle made by the given vector will be 45°.

Explanation:

Given vector A = i + j

From a general form of vector written as vector V = xi + yj , when the given vector A= i + j is compared.

We get,

x = 1 and y = 1

And we know,

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

Tanθ = Vertical component / Horizontal component

Tanθ = 1

$θ = 45°$

Hence, the angle (θ) made by the vector A = i + j with the x-axis is 45°.
