Thanks
my pleasure
I still have a doubt... Are considering this lens to be concave?!
no it is concave because in the question it is given that the image is formed in the front of the lence so it is considered as convex lense
o... okay
otherwise the focal length would be negative if it is concave lens
hope it helps you
