43. A vector has magnitude 20 N and an x-component of -12 N. If the vector lies in the second quadrant its y-component is

A. -16 N
B. +16 N
✓
C. +12 N
D. 0 N

📝 Explanation

(V_y=sqrt{20^2-12^2}=16) N. In quadrant II the y-component is positive.

📖 Additional Information

  • -16 N
  • +16 N
  • +12 N
  • 0 N

(V_y=sqrt{20^2-12^2}=16) N. In quadrant II the y-component is positive.
