2.An object is placed 7.0 cm away from a converging lens with a focal length of 7.0 cm. Find the distance to the image in the following lens problems and state whether the image is virtual or real AND whether it is upright or inverted.

3.An object is placed 65 mm away from a diverging lens with a focal length of 30. mm. Find the distance to the image in the following lens problems and state whether the image is virtual or real AND whether it is upright or inverted.

4.An object is placed 12 cm away from a diverging lens with a focal length of 6.0 cm. Find the distance to the image in the following lens problems and state whether the image is virtual or real AND whether it is upright or inverted.

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
