From the lens equation calculate the position of the following images produced by a convex lens.
Draw a ray diagram in each case and state whether the image are real or virtual and also if they are
upright or inverted
a. U= 5 cm and f= 2 cm
b. u = 10mm; f = 15mm
c. u = 3 cm ; f = 4 cm
Calculate the position of the images formed by the following concave lenses.
a. For an object with u = 6 cm if the focal length is - 2 cm
b. For an object with u = 4 cm if the focal length is -8 cm
c. For an object with u = 240mm if the focal length is - 8 cm

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
