1.	an object 3 cm high is placed at a distance of 10cm in front of a concave mirror of focal length 20 cm find the position nature and size of the image
Answer» 10cmf=20cmBy mirror formula1/-f=1/-u+1/-v1/-20=1/-10+1/-v1/v=1/-10+1/201/v=-2+1/201/v=-1/20v=-20The IMAGE will form 20 CM BEHIND the mirror
