. The electron and proton in a hydrogen atom are separated on the average by a distance of 5.3x10-' m (see figure below).
Assuming the orbit of the electron to be circular,
a) what is the electric force on the electron?
b) What is the speed of the electron's orbital speed?​

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
