The charge on the rod is shared between the rod and the sphere when they are in contact with each other. However, on grounding the charge will flow to the earth and the charge on the sphere becomes zero

When u bring a (+)ve charged rod near a metallic sphere the electron start to accumulat at that side of the sphere (causing that side of sphere to get partial (-)ve charge) while the other side gains a (+) charge when it is grounded or earthed the charge flows from conducter to earth and net charge becomes zero on the surface of conducter U can study this in detail in h c verma its an important topic

Charging a Metal Sphere by Contact
To understand the process of charging a metal sphere by contact using a positively charged rod followed by grounding, we need to consider the transfer of charge between objects.
Positive Charge Transfer
When a positively charged rod comes into contact with a neutral metal sphere, electrons from the sphere are attracted to the rod, leaving the sphere with a net positive charge. This is because electrons are negatively charged and will move away from the positively charged rod.
Grounding Process
After the metal sphere has been positively charged, grounding it involves connecting it to the Earth. Since the Earth is a vast reservoir of charges, it can supply or accept electrons easily.
Resulting Charge in the Metal Sphere
When the positively charged metal sphere is grounded, electrons from the Earth flow into the sphere to neutralize the positive charge. This results in the metal sphere having a zero net charge.
Therefore, the correct answer is 'Zero' because the metal sphere ends up with no net charge after the process of charging by contact using a positively charged rod followed by grounding.
