AA Physics Addition of Vectors (Rectangular Components
nmdcat.online August 7, 2026

24. A vector has components 4 N and 3 N. If its x-component is doubled while its y-component remains unchanged the new magnitude is

A. 5 N
B. 7 N
C. (sqrt{73}) N
✓
D. 12 N

📝 Explanation

The new components are 8 N and 3 N. Thus (R=sqrt{8^2+3^2}=sqrt{73}) N.

📖 Additional Information

  • 5 N
  • 7 N
  • (sqrt{73}) N
  • 12 N

The new components are 8 N and 3 N. Thus (R=sqrt{8^2+3^2}=sqrt{73}) N.
