Answer: Option (c) is the correct answer
Explanation:
It is known that when a neutral object comes in contact with a charged object then an opposite charge develops on the neutral object. But this development of charge occurs only when both the objects come in contact and if they are not in contact with each other then there occurs no charge on the neutral object.
As in the given situation, negatively-charged glass rod is brought near, but does not touch the sphere. So, there will occur no charge on the sphere.
Thus, we can conclude that final charge on the sphere is neutral.

Answer:
Correct Answer is positive force → balanced force → negative force
Explanation:
When Diego gives a big lift to the piano with the help of pulley system that time, initially piano moves upward so positive force acts on it.
Later, Piano stops, in this condition balanced force act on it since force applied by Diego is balanced by gravitational force of earth.
After some time piano starts falling in this condition negative force will act on the piano. In this condition, gravitational force will acts on piano in downward direction.
