Question

5. A charge of 2.00 ?0is placed at the origin, and a charge of 4.00 ?C is placed at 1.5 m. Locate the point between the two charges where a charge of 3.00 uC should be placed so that the net electric force on it is zero. 6. A compound microscope consists of two converging lenses (the objective and the eyepiece) placed 7.0 cm apart. If the first lens (objective) has a focal length of 2.8 mm and the second lens (eyepiece) has a focal length of' 3.3 cm, what would be the location of the final image of an object placed 3.0 mm from the objective lens? Describe the image. 7. The dielectric of a parallel plate capacitor is to be constructed from glass (Kd 4.6). The of each plate is 0.50 m2. A) What thickness should the glass have if the capacitance is to be 0.10 microfarad? B) What is the charge on the capacitor if connected to al2-volt battery 8. A light ray of wavelength 589 nm is incident on glass (from air) with an angle of 30. The index of refraction of the glass is 1.52. a) What is the angle of refraction? b) What are the speed and wavelength of the light inside the glass?
