Use the diagram below (four forces 2sqrt3N, 10N, 3sqrt3N and 6N acting on a particle P) to answer this question. The resultant of the four forces is
- A. 10sqrt3 N
- B. 10NCorrect
- C. 5sqrt3 N
- D. 5N
Explanation
Resolving each force into horizontal and vertical components and summing gives total horizontal = 8.66N and total vertical = 5N. Resultant = sqrt(8.66^2+5^2) = 10N.
