The resultant of two forces acting in opposite direction is $10N$. If these forces act perpendicular to each other their resultant will be $50N$ the magnitude of these forces will be:-

Q. If two forces act in opposite direction then their resultant is $10N$ and if they act mutually perpendicular then their resultant is $50N$. Find the magnitudes of both the forces.

Q. Two forces, while acting on a particle in opposite; directions, have the resultant of $10N$. If they act at right angles to each other, the resultant is found to be $50N$. Find the two forces.

Q. A cubical block is subjected to three forces $F_1=20\text{N}$ acting at an angle of ${45}^{\circ }$ with horizontal and lying in the diagonal plane of the cube, $F_2=30\text{N}$ along $y-$axis and $F_3=40\text{N}$ acting in the negative $x-$direction as shown. Find the magnitude of friction force acting on the body.

Q. Two like parallel forces $20N$ and $30N$ act at the ends $A$ and $B$ of a rod $1.5m$ long. The resultant of the forces will act at the point:
