The fig shows wheel of radius 5cm that can rotate freely about, the point O. It is in equilibrium due to force F₁ and F₂ acting on it.Which one of the force is greater and what is the ratio of the two force?

The forces F1 and F2 are perpendicular to each other.
The forces F1 and F2 are balanced by equal and opposite forces at O acting on the wheel by the support at O.
The moments of forces by F1 and F2 about O balance each other. The reason is that wheel is in static equilibrium.
let the radius of the wheel = R.
F1 * R = F2 * OO'
OO' / R = F1 / F2
As OO' is less than R, F1 is less than F2.
