Hii mate...
Sorry for writing.. It's too cold here
See the attachment for answer..
NOTE: In the second case our Object distance(u) is 20 cm and our focal length is also 20cm it mean the object is at focus and according to rule we know that if an object is placed at focus then its image forms at Infinity... That's why in second case we get our image distance (v) as 0(zero)..And ya here mirror is Concave mirror.. Becoz Convex mirror never produces real image.
Hope u understand!!!
