23. Drаw the lens diаgrаm belоw: (be sure tо use a straight edge) a) Calculate the image distance fоr a focal length of 7.0 cm and an object distance of 16.0 cm. (4 pts) b) Draw the three principle rays to find the image, draw in the image and the focal point. Use the information you calculated in "a" to label the diagram properly. (6 pts) c) Calculate the magnification and image height for an object height of 4.0 cm. (8 pts) 24. Charge 1 is 25.0 cm from point P and charge 2 is 15.0 cm from point P. a) Calculate the magnitude and direction of the total electric field at point P in the diagram above. (Indicate the direction as an angle above or below the horizontal) (14 pts) b) Calculate the electric potential at point P in the diagram above. (8 pts) 25.
