Answer 1

Answer:

Given that:

u=-10cm

f=-15cm

Using lens formula:

1/f=1/v-1/u

1/v=1/f+1/u

=-1/15-1/10

or v=-6cm

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

-6/-10=h'/h

3/5=h'/h

Size of image h'=3/5 h

A virtual and erect image is formed at a distance of 6cm from the lens.

Explanation:

For magnification use formula : m = image size / object size or m = image height/object height
