Solve the following question given below:
Question: Determine the force of electrostatic interaction between the electron and the nucleus of a singly ionized Helium atom. Singly ionized Helium atom contains two protons in the nucleus, and an electron orbiting around it. The mean distance of electron from the nucleus of the atom is 2 x 10-10 (K= 9 x 109 Nm2/C2, e=1.6 x 10-19).
This is a physic question, reply as soon as possible. Thank you.
