Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

Helium is the second element on the periodic table, meaning it contains two protons in its nucleus. Normally, helium contains two electrons that orbit the nucleus, however you can ionize the helium, which is stripping an electron from the atom. With 2 protons in the nucleus of the atom, what will be the centripetal acceleration of the electron in an ionized helium atom? ( the electron or it’s at a radius of 29.3 x 10^-12 m around the nucleus)
