Expert Solution
Step 1
In this question, a nucleus carrying 11 protons is placed along the positive X-axis at a distance of from the origin and an electron is also placed at the origin.
Step 2
Hence, the point where electric field due to this system is zero will be on the negative X-axis nearby the electron to balance electric field due to the nucleus as well as the electron.
Assuming the point to be situated at a distance of from the electron on the negative X-axis. Thus, its distance from the nucleus will be .
These distance are measured in angstroms.
