Physics 212 - Module 5 Hands On Activities Packet2. A mass spectrometer is used to determine the mass of theions in a sample. Once the mass of the ions are known onecan determine what molecular composition of the sample.The Behrend chemistry department has several massspectrometers.A new singly charged ion (the sign of the charge is unknownbut we know it is either te or-e) enters a velocity selectoras shown with crossed electric and magnetic fields ofmagnitude E and B. Only ions with the selected speed thenleave through the right hole and enter a region with thesame magnetic field B but no electric field. The magneticforce then causes the charges to move in a semi-circularpath of radius r as shown. By measuring r one candetermine the mass of the ions.a. Is the ion positive or negative?• 8 times as large• a factor of √2 as large• 1/2 as largeb. Determine the mass of the ion in terms of e, B, E and/or r. Show work.

Directions: Assume, unless otherwise specified, that all numbers have at least 3 significant figures. You may work together, but make sure that you are working--not just watching. The magnitude of the force of attraction between the proton and electron in a hydrogen atom is: F = where e is the magnitude of the charge, k is a constant, and r is the radius of the circular orbit. Assume the proton is fixed in place and the electron is in a circular orbit of radius ri. The electron then "jumps" to a new, smaller radius r2. What is the change in the total mechanical energy of the system (in terms ri, r2, e, and k)? Hint: Use dynamics to calculate the kinetic energy for the electron in the initial and final orbits, then calculate the potential energy in both orbits (you will need to develop an expression for the potential energy and remember the force is attractive). Do you know what form the change in mechanical energy takes?

A thin spherical shell with radius R₁ = 4.00 cm is concentric with a larger thin spherical shell with radius R2 = 6.00 cm. Both shells are made of insulating material. The smaller shell has charge q₁ = +6.00 nC distributed uniformly over its surface, and the larger shell has charge q2 = - 9.00 nC distributed uniformly over its surface. Take the electric potential to be zero at an infinite distance from both shells. - For related problemsolving tips and strategies, you may want to view a Video Tutor Solution of Potential vsurface and field magnitude esurface at the surface. ▶ Part A Part B
Please solve it: 1. Measure the capcitance of the capacitor if the space between the plates is filled with air. 2. Find the amount of charge that will appear on the plates if potential difference of 150V is applied. 3. If the distance between the plates is 3.0 times the old distance and wax is inserted the new capacitance becomes double of the old capacitance. Find the dielectric constant of the wax.
In a Millikan experiment, two horizontal parallel plates are 3.5 cm apart.

Determine the charge on the sphere.b. What is the magnitude of the sphere's excess or deficiency of electrons?
Answer the following questions. 1. Why does the voltage across the resistor for charging and discharging processes change the sign from positive to negative? Hint: think about the direction of current. 2. Does the voltage V across the resistor for charging and discharging obey by the same equation: V = Vo eRC 3. What is the sum of the voltages across the capacitor Vc and across the resistor VR at any point in time during the charging and discharging processes?
