Question

20. A displacement vector of magnitude 4 makes an angle 30° with the x-axis. Its rectangular components in
X-y plane are

Answer 1

Answer:

$horizontal \: component = 4 \cos(30 ) \\ = 4 \times \frac{ \sqrt{3} }{2} \\ \\ = 2 \sqrt{3 }$

$vertical \: component = 4 \ \sin(30) \\ 4 \times \frac{1}{2} \\ = 2$
