yo i need help om physics, specifically on the electricity unit. The charge by induction part is confusing as shit and i don't get what the ground does.

Let me explain with an example.
Say, a negatively charged rod was held near a neutral sphere. In that case, the electrons would be rearranged in such a way that the side of the sphere that is near the rod would have an deficit of electrons (i.e. "more positives"), and the "negatives" would be on the other side. The grounding is done to change the overall neutral charge of the sphere to positively charged. A grounding wire is usually attached to the side with the side with an excess of electrons (i.e. "more negatives") to get rid of those negatives and make the overall charge positive. Grounding is just a way of providing an alternative "escape route" for electrons (or charges). Therefore, when the grounding wire and the rod are removed, the sphere will have a positive net charge.

I hope this helps.
