If the greatest and the least resultants of two forces are

{P}

and

{Q}

respectively, then the resultant of these forces, when acting at right angles, will be

View answer and explanation

Correct option: D

\sqrt{\frac{\left({P}^2+{Q}^2\right)}{2}}

The correct answer is D (

\sqrt{\frac{\left({P}^2+{Q}^2\right)}{2}}

) because it correctly calculates the resultant of two forces acting at right angles, given their greatest and least resultants.
