Question

You have an atomic nucleus with 9 protons, placed at x = 7.5 Angstroms. What TWO values of x (along the x-axis) will the total electrostatic potential V be equal to zero?

		-0.28 Angstroms and 0.53 Angstroms
		0.28 Angstroms and -0.53 Angstroms
		-0.94 Angstroms and 0.75 Angstroms
		0.94 Angstroms and -0.75 Angstroms

Expert Solution

Step 1

Consider the case when the electric potential is zero in a place between the position of electron and atomic nucleus.

Let, the distance from the electron be 'd' , then the distance of that point from the atomic nucleus is = ( 7.5 - d )

So, the electric potential at that point is :
