Question

7. An electron has been placed at the origin. The grid spacing is 1 Angstrom per small square this time. You put a nucleus with 9 protons on the x-axis at x = 3.0 Angstroms. There will be a place on the x-axis where the total electric field is zero. At what value of x does this occur?

		0.18 Angstroms
		-1.50 Angstroms
		-0.60 Angstroms
		0.36 Angstroms

Expert Solution

Step 1

Given that,

An electron is placed at the origin,

And a nucleus is placed at $r = 3 (\dot{A})$

There are 9 protons in the nucleus, so the charge of the nucleus is $q_{1} = 9 e$

Let at point P the net electric file is zero which is at x distance from the origin.
