Question

A object is of height 6cm is placed perpendicular to the principal axis

Answer 1

Step-by-step explanation:

H=6cm

f= -5cm

u= -10cm

=>1/v=1/u+1/f

=1/-10+1/-5cm

=-1-2/10cm

=-3/10cm

=>v =-10/3cm

=-3.33cm

Hence,the image will form at the same side of object,3.33cm away from the lens

Now,m=h'/h=v/u

=h'/6=(-10/3)/-10

=h'/6=1/3

=h'=2 Ans

Hence the size of image is 2cm

nature of image is real and inverted
