Two forces of magnitude 3H and 4H are applied to a material point, the angle between the vectors of these forces is 90 °.

Two forces of magnitude 3H and 4H are applied to a material point, the angle between the vectors of these forces is 90 °. The resultant of these forces.

Since the forces are applied to one body at a right angle, the resultant force will be directed in accordance with the rule of the triangle, and the modulus of the resulting force will be found according to the Pythagorean theorem, note that the triangle is Egyptian, then the modulus of force is 5N.
