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.
a) what is the electric force on a proton 9.0 fm from the surface of the nucleus?
express your answer in newtons.
b) what is the proton's acceleration?
express your answer in meters per second squared.
2) two 3.5-cm-diameter disks face each other, 2.0 mm apart. they are charged to ± 11 nc .
a) what is the electric field strength between the disks?
express your answer in newtons per coulomb.
b) a proton is shot from the negative disk toward the positive disk. what launch speed must the proton have to just barely reach the positive disk?

Ответ:
-- Slope of the line is constant, so the object's speed is constant.
Passing through the origin . . . . .
-- When time was zero, position was zero.
-- So the object was moving before the starter fired his pistol, but it crossed
the starting line, at its constant speed, just as the shot sounded.
