Question

Describe balanced forces with the help of two examples.

Answer

If the resultant of various forces acting on a body is zero, the forces are said to be ‘balanced forces’. These forces do not change the speed but usually change the shape of an object.

Examples:

(a) Consider a wooden block lying on a table, the strings tied to its two opposite faces, as shown in the figure.

balanced forces

If we pull at point P, it begins to move towards left. If we pull at point Q, it begins to move towards right. But if we pull from both the sides with equal force, the block does not move. The two forces have now balanced each other.

(b) In a tug-of-war, the two teams pull the rope with equal effort; the rope is not moved in any direction. This is clearly because the forces exerted by the two teams are equal and opposite and thus get balanced.

Two friends were going for a short tour and on the way the car suddenly stopped. Both of them managed to push the car of mass 1100 kg at a uniform velocity along a level road. In the meantime a villager came to help them and the same car was now pushed by three persons at an acceleration of 0.2 m/s2 . After reading the passage carefully answer the following questions: (𝒊) With what force does each person push the car? (𝒊𝒊) Which value is promoted here? (Consider that each person pushes the car with the same efficiency.)
