The "size" of the atom in Rutherford's model is about 1.0 ✕ 10−10 m. (a) Determine the attractive electrostatic force between an electron and a proton separated by this distance. N(b) Determine (in eV) the electrostatic potential energy of the atom. (Assume the electron and proton are again separated by the distance stated above.) eV

In the Millikan oil drop experiment tiny charged oil droplets generated by a spray are allowed to fall under gravity through a hole in a top electrode, T, towards a bottom electrode B separated from T by 1 cm. When a holding voltage Vh = +0.25V is applied between T and B the droplets are seen to be suspended motionless between the electrodes. What is the specific charge of the droplet q/m?

Four different particles are trapped in one dimensional wells with infinite potential at the walls and zero potential inside. The masses of the particles and their energy level, n , are given by: 1.  mass=m, n=1 2. mass=2m, n=2 3. mass =3m, n=3 4. mass=4m, n=2 All these wells have the same length L. Rank the kinetic energy of the particles in order of size, smallest to largest. Group of answer choices E3 <E1<E2<E4 E1 = E4 < E2 < E3 E4 <E3 <E2 = E1 E1 < E2 = E4 < E3 E1 < E2 = E3 <E4

10) Now you have a nucleus with 13 protons at x = 6.2 Angstroms on the x-axis. How much work would it take to bring in ANOTHER nucleus with 7 protons from 1 m away and place it at y = 8.0 Angstroms on the y-axis?     70.0 eV     116.7 eV     -12.6 eV     129.3 eV
