Chapter 30, Problem 56PE

Integrated Concepts
In a Millikan oil-drop experiment using a setup like that in Figure 30.9, a 500-V potential difference is applied to plates separated by 2.50 cm. (a) What is the mass of an oil drop having two extra electrons that is suspended motionless by the field between the plates? (b) What is the diameter of the drop, assuming it is a sphere with the density of olive oil?

In the Franck-Hertz experiment, explain why the small potential difference between the grid and collector plate is useful. Redraw the data of Figure the way the data would appear without this small retarding potential.
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? Select one: a. 0.16 C/kg b. 0.392 C/kg с. 2.7 С/kg O d. 1.5 C/kg
Please answer with a complete solution   An electron has a velocity of 1.5 x 107 m/s at right angles to the uniform electric field between two parallel deflecting plates of a cathode ray tube shown below. If the plates are 2.5 cm long and spaced 0.9 cm apart, and the potential difference between the plates is 75 V, calculate how far the electron is deflected sideways during its movement through the electric field.Assume electronic charge to be 1.6 x 10-19 C and the mass of electron is 9.1 x 10-31 kg.
