Question

the maximum and minimum magnitudes of the resultant of two force are 3N and 5N respectively . Find the magnitude of resultant force when act orthogonally to each other.

Answer 1

Answer:I think this can help you

Explanation:

The resultant of two forces acting on the same point is maximum when the forces are acting in the same direction and minimum when they operate in opposite direction.

When the two forces are acting in the same direction the angle between the direction to the two forces is 0. In this case the resultant force is sum of the two forces and its direction is same as the two independent forces.
