Question

A vector of magnitude is 10 unit makes an angle of 30 degree with x axis. find its components along x axis and y axis​

Answer 1

Answer:

x component = 10 × cos 30 °

                       = 10 × $\sqrt{3}$ /2

                      = 5  $\sqrt{3}$

y component = 10 × sin 30 °

                      = 10  × 1 / 2

                      = 5

Answer 2

Answer:

The correct answer of this question is the vector's x and y components. y component = 10 sin Ф .

Explanation:

Given - A vector of magnitude is 10 and an angle of 30 degree with x axis.

To Find - Find the components along x axis and y axis​ .

The vector's x and y components. y component = 10 sin Ф, where sinФ is the vector's angle with the x-axis.

So,

x component which is = 10 × cos 30 °

                      = 10 ×  $\sqrt{2}$

                     = 5  

y component = 10 × sin 30 °

                     = 10  × 1 $\sqrt{2}$

                     = 5
