Medium

Three small, lightweight insulated spheres, $L$ , $M$ , and $N$ , each carry a non-zero net static charge.

It is observed that:

Which of the following statements correctly describes the relative numbers of protons and electrons within the spheres?

Spheres $L$ and $M$ both have more electrons than protons; sphere $N$ has more protons than electrons.

Spheres $L$ , $M$ , and $N$ all have equal numbers of protons and electrons.

Sphere $L$ has more protons than electrons; spheres $M$ and $N$ both have more electrons than protons.

Sphere $L$ has more electrons than protons; spheres $M$ and $N$ both have more electrons than protons.
