What is the electric force on a proton 1.8 fm from the surface of the nucleus? hint: treat the spherical nucleus as a point charge the nucleus of a 125 xe 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 express your answer to two significant figures and include the appropriate units. ? value units f = request answer submit part b what is the proton's acceleration? express your answer to two significant figures and include the appropriate units.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
