###### Question:

A square metal frame of resistance 10 ohm is pushed with a force of 20 N into a homogenous magnetic field of 2 T with a constant speed of 20 m/s. What is size of this frame if the current generated in it is 5 mA? An optical system is made of converging and diverging lenses with focal distances 12.5 mm and 54 mm respectively. How large is the final mage of a 7 mm object placed at a distance of 23 mm from the converging lens? The distance between the lenses is 66 mm. Plot the images formed by two lenses in scale on the drawing below and compare the calculated values (image sizes and image distances) with those on the drawing. Find total magnification of the optical system.
