Final answer:
The magnitude of the electric field produced by an electron at the center of its orbit around a proton can be calculated using Coulomb's law, where the electric field (E) is E = k * |q| / r^2 with known values for the electron's charge and the orbit's radius.
Step-by-step explanation:
To determine the magnitude of the electric field that an electron produces at the center of a circular orbit (which can be modeled like a clock face with the proton at the center), we can apply the principle that the electric field (E) produced by a point charge is given by Coulomb's law. Specifically, the magnitude of the electric field due to a point charge is E = k * |q| / r2, where k is Coulomb's constant (8.99 × 109 N·m2/C2), q is the charge of the electron (-1.602 × 10-19 C), and r is the distance from the charge to the point where the field is being calculated—in this case, the radius of the electron's orbit (5.28 × 10-11m).
Calculating this, we get:
E = (8.99 × 109 N·m2/C2) * (1.602 × 10-19 C) / (5.28 × 10-11m)2
The calculations yield the magnitude of the electric field at the center of the clock face due to the orbiting electron.
