The nucleus of a 125xe atom (an isotope of the element xenon with mass 125 u) is 6.0 fm in diameter. it has 54 protons and charge q=+54e (1 fm = 1 femtometer = 1×10−15m.) hint: treat the spherical nucleus as a point charge. part a part complete what is the electric force on a proton 1.0 fm from the surface of the nucleus? express your answer in newtons. fnucleusonproton f n u c l e u s o n p r o t o n = 780 n submitprevious answers answer requested part b what is the proton's acceleration? express your answer in meters per second squared.

A:

B:

Explanation:

Given:

Part A:

Coulomb's law states that the electric field due to a charged sphere of charge Q at a point r distance away from its center is given by

where, k = Coulomb's constant whose value =

Therefore, the electric field due to the nucleus at the proton is given by

Therefore,

The electric force on a charge q due to an electric field is given as  

For the proton,

Thus, the electric force on the proton is given by

Part B:

According to Newton's second law,

where, a is the acceleration.

The mass of the proton is

Therefore, the proton's acceleration is given by

the answer is b
