Equilibrium — Three ForcesMediumQuestion 30253

Question

Three forces act on a body in equilibrium. Two forces are 6 N and 8 N perpendicular to each other. The third force is:
  1. A
    14 N
  2. B
    2 N
  3. C
    10 N
    Correct
  4. D
    √(48) N

Correct answer

10 N

Explanation

Resultant of 6 N and 8 N (perpendicular) = √(36+64) = 10 N. For equilibrium, the third force must be 10 N in the opposite direction.
