Question

The miminum number of unequal forces in a plane that can keep a particle in equilibrium is

Answer 1

Answer:

3

Explanation:

Consider a single force acting n a particle.

When a single unbalanced force acted upon a particle, its equilibrium is disturbed.

To make the particle in equilibrium, equal and opposite force on same plane must be applied to the particle.

As per condition, forces must be unequal.

Thus, we can split this equal and opposite force into two forces whose magnitudes are different.

Thus these 3 unequal forces will keep the particle in equilibrium.

∴ Minimum three forces in same plane are required to keep the partile in equilibrium.
