Physics · MOTION IN A PLANE

A force vector \( \mathbf{F} \) of magnitude \( 20\text{ N} \) makes an angle of \( 30^\circ \) with the horizontal x-axis. Its vertical y-component \( F_y \) is equal to:

1. A
   \( 10\text{ N} \)
2. B
   \( 10\sqrt{3}\text{ N} \)
3. C
   \( 20\text{ N} \)
4. D
   \( 5\text{ N} \)
