Question

20. A displacement vector of magnitude 4 makes an angle 30°
vertor of magnitude 4 makes an angle 30' with the x-axis. Its rectangular components in
X-y plane are
(1) 2√3,2
(2) 473,4
(4) 534
​

Answer 1

Answer:

1) 2√3 and 2

Explanation:

Since the vector makes 30 degrees with the positive x axis, its components will be given by

(Magnitude) * cos30 - along x axis

Magnitude*sin30- along y axis

= 4*√3/2 = 2√3

and

4*1/2 = 2
