In this problem, we are given that there is a concave mirror, and the focal length of this concave mirror, well, that's given as 10 centimeters.
00:13
So here we know that the focus of the concave mirror that lies to the left, and we take all the distance measured to the left as negative, and all the distance measured to the right will be positive.
00:24
And thus the focal length, it will be negative as the focus lies to the left of this mirror, and it is, it will be minus 10 centimeter instead.
00:34
And this concave mirror, it creates a real image, which is at a distance of 30 centimeters away from the pole of this mirror.
00:44
So the image distance, that will be minus 30 centimeter because real image is formed on the same side where the object is kept in case of concave mirror.
00:55
And we are required to determine the distance of the object from the mirror...
