Here in this question we are given the distance between two lens is given.
00:09
The distance between lens is equal to 22 cm.
00:16
The focal length of each lens is given.
00:19
Both the lens have same focal length and the value is 8 .1 cm.
00:24
Now here an object is kept at a distance from the left side lens.
00:33
So the distance of object from the left lens is given in the question which is equal to 35 cm.
00:47
Let this be d0 that is distance of the object from left lens.
00:53
First we need to find the image distance from the first lens.
01:02
When an object is kept near the left lens an image is formed.
01:06
So the distance of image from the first lens is to be calculated.
01:11
So here the distance of image di initially is equal to focal length of into the distance of object from left lens divided by the distance of object from left lens minus its focal length.
01:28
So this is equal to focal length is 8 .1 into 35 cm divided by 35 minus 8 .1...
