Question

A vector of magnitude 13 makes an Angle 65.37 with the X-axis .what is its components along positive y- axix​

Answer 1

The component of a vector along the y axis is given by the sin of the angle it makes with the x axis

Answer 2

Explanation:

Given that,

Magnitude of the vector in x -axis, x = 13

Angle with x- axis, $\theta=65.37^{\circ}$

We need to find the component along y- axis. The magnitude of the vector in y- axis is :

$y=a\ sin\theta$

$y=13\ sin(65.37)$

y = 11.81

So, the component along positive y- axis is 11.81. Hence, this is the required solution.
