23. а) A diverging lens is plаced in а lens hоlder оn an оptical bench. What is the the image distance if the diverging lens has a focal length of 10.0 cm and the object is set at a distance of 5.0 cm on the left side of the lens on the optical bench. (4 pts) b) Draw a ray tracing diagram for the arrangement described above. Draw the three principle rays and include the near and far focal points in your drawing. Be sure to identify the object and image in your drawing. Use the information you calculated in "a" to label the diagram properly. (6 pts) c) What type of image is formed by the diverging lens and what is its orientation? (4pts.) d) Calculate the magnification and image height for an object height of 4.0 cm. (4 pts) 24. Charge 1 is 15.0 cm from point P and charge 2 is 5.0 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. Draw the electric field lines for two equal negative charges. Indicate the direction of increasing potential. (4pts) 26. a) Draw the two possible arrangements that can be made with a 10.0 uF and 2.50 uF capacitors. Be sure to label each arrangement and use the correct symbols for the capacitors and values. (4 pts) b) Calculate the total capacitance for each of the arrangements drawn above? (4 pts) c) Find the energy stored in the capacitors if they are connected in series to a 6.0 V lantern battery and the energy stored for a parallel connection. (4pts)
