Answer» This ONE is easy forsooth! Here we have, U(object distance) = -20cm F(focal length) =+25cm Now we will apply the MIRROR formula ie [math]1/f=1/v+1/u[/math] 1/25=-1/20+1/v 1/25+1/20=1/v Lcm(25,20) is 100 4+5/100=1/v 9/100=1/v V=100/9 V=11.111cm Position of the image is behind the mirror(11.111cm) and the image is diminished in nature.
