Aplastic rod that has been charged to -15.0nc touches a metal sphere. afterward, the rod's charge is -10.0nc. part apart complete what kind of charged particle was transferred between the rod and the sphere? what kind of charged particle was transferred between the rod and the sphere? electrons protons previous answers correct

Negatively charged particles (electrons)

Explanation:

Plastic rod is charged -15.0 nC. It is clear that the charge on the rod is negative so the rod has gain excess of electrons.

When the rod touches a metal sphere charge on the plastic rod remains -10 nC, i.e. negative charge on the rod decreases. This is because negatively charged particles (electrons) are transferred from the plastic rod to the metal sphere.

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.
