Two forces act simultaneously on a material point. F1 = 3, F2 = 4.determine the value of the resultant if the angle between the forces is 270 degrees.

To add the forces acting on a material point, F1 = 3 H and F2 = 4 N, it is necessary to use the parallelogram rule:
R = sqrt (F1² + F2² + 2 * F1 * F2 * cos α), where α is the angle between the forces (α = 270º).
Let’s calculate the resultant force:
R = sqrt (F1² + F2² + 2 * F1 * F2 * cos α) = sqrt (3² + 4² + 2 * 3 * 4 * cos 270º) = sqrt (9 + 16 + 2 * 3 * 4 * 0) = sqrt (25) = 5 N.
Answer: The net force is 5 N.
