Question

how can we make a body positive or negative charge​

Answer 1

Answer:

In order to tell the sign of an object charge, you need another object with a known positive or negative charge. If you rub a piece of glass with silk, it will have a positive charge (by convention). If you rub a piece of amber with fur, it will have a negative charge (also by convention). Use whatever you have handy
