The resultant of two forces 12N and 5N is 13N. What is the angle between the two forces?

  • 0o
  • 45o
  • 90o checkmark
  • 180o

The correct answer is: C

Explanation

R2 - P2 + Q2 = 122 + 52
= 144 + 25 = 169
âˆīR = √169 = 13N
âˆī angle between the forces is 90o

There is an explanation video available .
