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? |

Answer» ces 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. |
