A thin lens has a focal length f = 1.0 x 10^2 cm. In order to ensure that the image is the same size as the object, where should the object be placed? That is, what is the object distance s?

Question 1 options:

	1.0 x 10^2 cm
	3.4 x 10^2 cm
	50. cm
	2.0 x 10^2 cm
	4.0 x 10^2 cm

An electron is moving in the positive x direction at a rate 3.0 x 10^5 m/s. A magnetic field persists in the space pointing in the positive z direction with a magnitude 0.80 T. What is the magnetic force on the electron (recall its charge is -1.60 x 10^-19 C):

Question 3 options:

	4.0 x 10^-14 N, pointing in the positive y direction
	4.0 x 10^-14 N, pointing in the positive z direction
	4.0 x 10^-14 N, pointing in the negative y direction
	4.0 x 10^-14 N, pointing in the negative z direction
	none of these

We have two small charges. The first is +8.0 nano C and the second is -2.0 nano C. The two are separated by a distance 4.0 m. The electric field in units of N/c at the midpoint between the two charges is:

Question 6 options:

	23
	3.6 x 10^-9
	1.4 x 10^5
	9.0 x 10^9
	1.4 x 10^4

A concave lens has a focal length of magnitude 10 cm. It is placed a distance of 25 cm from a concave mirror with a focal length of magnitude 15 cm. An object is set a distance of 22 cm in front of the lens. The observer is at the same location as the object, so the light from the object goes through the lens, reflects off the mirror, and comes back through the lens to the observer. Draw the...
