Solution
Step1: Muscular force
Muscular force is a type of contact force (any force which acts after contact).
When any force is applied by muscles like arms or legs is known as muscular force.
If you lift a brick from the ground, then your muscles do the necessary work for lifting it hence, here muscular force is applied by arms.
Step2: Gravitational force
The gravitational pull of the earth is a type of attraction force the earth exerts on an object or the object exerts on the earth.
It must be equal to the mass of water inside the bucket multiplied by the acceleration due to gravity.
It always acts toward the earth's core.
Step3: The forces acting on the bucket do not bring a change in its state of motion.
Forces acting on a plastic bucket containing water held at some level from the ground level in our hand are muscular forces and gravitational forces.
Both the forces are the same in magnitude but in opposite directions and thus they cancel each other out. Therefore there is no change in the state of its motion.
Thus, The forces acting on the plastic bucket cancel out each other That's why the forces acting on the bucket do not bring a change in its state of motion.
