When we rub our dry hair with a comb, the comb becomes _____ charged. (negative or positive)

When we rub a balloon or comb on dry hair, electrons in the outer orbitals of the hair fibers can be pulled off onto the comb surface. The comb that became negatively charged will attract other objects, like paper by inducing a temporary charge.

[Extra information:

When two objects are rubbed against each other, one object is prone to lose some electrons and becomes more positively charged, while another object is prone to gain electrons and becomes more negatively charged. This build-up of excess charge is what is called static electricity.

As the name suggests, static means not moving. Static electricity is an electrical static charge, that doesn't move.]
