Question

A positive ion is an atom that has lost some of itselectrons. A singly-charged helium positive ion (He +) iscomposed of a helium nucleus (made up of 2 protons and 2 neutronshaving a total mass roughly 8000 times larger than an electron) anda single electron orbiting about it. The force that theelectron in this ion exerts on the helium nucleus is A) only about 4000 times smaller than the force exerted by thehelium nucleus on the electron since the neutrons do not experienceCoulomb forces B) roughly 8000 times smaller than the force exerted by thehelium nucleus on the electron C) equal to the force exerted by the helium nucleus on theelectron
D) only about 4000 times larger than the force exerted by thehelium nucleus on the electron since the neutrons do not experieceCoulomb forces E) roughly 8000 times larger than the force exerted by thehelium nucleus on the electron Why?

Explanation / Answer

Option ( C ) is correct. i.e. equal to the force exerted by the helium nucleus onthe electron. Since the force is depend on charges and distance between thecharges
