Question

Use the diagram below. Calculate x component of the Force 15 N .
A 15 N Cos 30 degrees
B 15 N Sin 30 degrees
C - 15 N Cos 30 degrees
D - 15 N Sin 30 degrees

Answer 1

B) 15 N Sin 30 degrees

This is the right answer because 15 N is in 4th quadrant and 30⁰ is the angle with y-axis which gives sin30⁰ as x component.
