Question

Can a body be in equilibrium when only one force acts on it? Explain.

Step-by-Step Solution

Answer

As the net force on the object is not zero, the body is not in equilibrium.

Step 1: Equilibrium

For an object to be in equilibrium, the net force on the object must be zero. The object in equilibrium can be stationary or moving at a constant velocity.

For example, an airplane moving at a constant velocity can be in equilibrium, as the lift produced by wings is balanced out with weight and thrust is balanced out with drag force.

Step 2: Given Case

In the given case, only one force acts on the body, imparting an acceleration. Hence, this body is not in equilibrium.
