A convex lens and a covex mirror are seperated by a dis†an ce of 10cm such that the reflecting surface of the mirror faces the lens .The image of an object placed in front of the convex lens at a dis†an ce of 20cm is found to coincide with the object If the focal length of the convex lens is 15cm determine the length of the mirror?
