Question

when an object is placed at a distace of 60 cm from a convex mirror, the magnification produced is 1/2. where should the object be placed to get a magnification of 1/3?

Answer 1

Answer:

Explanation:

        they said that -v/u = 1/2  i.e, v = -u/2 = -30

               put the value in mirror formula, 1/f = 1/v +1/u

           you will get f here for the next -v/u =1/3 i.e,  v= -u/3

               put the obtained value of f and find u

          solve to get the answer hope it helps............
