Question

A proton and an electron in a hydrogen atom are separated on the average by about 5.3 × 10−11 m. What is the magnitude of the electric field set up by the proton at the location of the electron? The value of the Coulomb constant is 8.99 × 109 N · m2/C2. Answer in units of N/C

Answer 1

Answer:

5.10¹¹ N/C

Explanation:

As we have a proton and a neutron, we can consider that they both have the same charge, this is:

e- = e+ = |1,6x10⁻¹⁹ C| , this number is in absolute value

Then, the formula needed to calculate the magnitude of the electric field from a charged particle is:

E= kqQ/r²

Where:

K= Coulomb constant

Q= charge  

r = distance between two charges

Then:  

E= 8.99x10⁹N/C²*(1.6x10⁻¹⁹C)/(5.3x10⁻¹¹m)²

E=5.12x1011 N/C

It is important that this value is a magnitude, it does not have any sign (positive or negative), for the magnetic field
