48. Two vectors have components ((10,10)) N and ((-6,2)) N. The direction of their resultant relative to the positive x-axis is closest to

A. 30°
B. 45°
C. 60°
D. 72°
✓

📝 Explanation

The resultant components are (R_x=4) N and (R_y=12) N. Therefore (tantheta=12/4=3), giving (thetaapprox71.6^circ), closest to 72°.

📖 Additional Information

  • 30°
  • 45°
  • 60°
  • 72°

The resultant components are (R_x=4) N and (R_y=12) N. Therefore (tantheta=12/4=3), giving (thetaapprox71.6^circ), closest to 72°.
