Question

a concave mirror produces a real image of half the size of object placed at 60 CM in front of it where should the object be placed to obtain a virtual image of double the size of object

Answer 1

❤ best Solution:❤

Given that,

Object distance u = –60 cm

then

⇒ V = 30 cm.

Now use mirror formula to find its focal length (f)



Again from question:-



Let object distance = –x



Then by using the mirror formula



Hence the required object distance = 120 cm
