Two forces corresponding to 8 and 6 N act on one body. The angle between the directions of forces is 90 °.

Two forces corresponding to 8 and 6 N act on one body. The angle between the directions of forces is 90 °. Find their resultant.

Since two forces acting on one body are directed at an angle of 90º to each other, then to find the resultant force we apply the Pythagorean theorem:
F² = F1² + F2², where F1 = 8 N, F2 = 6 N.
F = sqrt (F1² + F2²) = sqrt (8² + 6²) = sqrt (64 + 36) = sqrt (100) = 10 N.
Answer: The net force is 10 N.
