When an object is placed at the proper distance to the left of a converging lens, the image is focused on a screen 30.0 cm to the right of the lens. A diverging lens with focal length f= -24 cm is now placed 15.0 cm to the right of the converging lens. a) How much do you need to move the screen farther to obtain a sharp image? Indicate if the screen should be moved to the right or to...

A) In the geometrical optics experiment, a student used a convex lens with 7 cm focal length to produce a large image of an object. The object was placed at a distance of 13 cm from the lens. Find the location of the formed image with respect to the lens (in cm). B) In the geometrical optics experiment, a student performed an experiment to measure the focal length of a convex lens. The object was placed at a distance of...

A +5.0-μC point charge is placed at the 0 cm mark of a meter stick and a -4.0-μC charge is placed at the 50cm mark. What is the net electric field at the 30cm mark? Please explain why we do not take into account the negative sign of the 4uc charge. don't just workout the problem I get that its kq/r2 + kq/r2.

55) A 0.15-N meter stick is suspended from a spring scale at its 25-cm mark. When an object of unknown mass is hung from the meter stick on the 10-cm mark, the meter stick is in equilibrium. Draw an extended-body force diagram for the meter stick and (a) determine the mass of the object and (b) the reading on the spring scale.
