The atom in an excited state has more energy and is less stable than the atom in the ground state.
A charged particle moving in a magnetic field experiences a force equal to:

Thus, the magnitude of the force that the proton experiences is given by:

The magnetic field is perpendicular to the proton's velocity, therefore, we have
. Replacing the given values, we obtain:

too much static electricity can cause a negative reaction such as the balloons repelling away from one another.
