Answer 1

if a ladder is not in equilibrium against a smooth vertical wall, then it can be made in equilibrium by increasing its angle of inclination.

Answer 2

Answer:

if a ladder is not in equilibrium against a smooth vertical wall, then it can be made in equilibrium by increasing its angle of inclination.

Explanation:

The ladder will slip because of the gravitational force acting on it the downwards direction. It is given by $Mgcosθ$, where M is the mass of the ladder and θ is the angle of inclination.

Change in length will have no effect in the force due to gravity. But when the angle of inclination is increased, it will cause the value of cosθ to decrease and hence, reducing the force due to the gravity.

So,we can say if a ladder is not in equilibrium against a smooth vertical wall, then it can be made in equilibrium by increasing its angle of inclination.
