Question

A Covex mirror is present 5m away
from a tree of height 2m. If the
focal length of the mirror is 1.5m
calculate the position and size of


the image​

Answer 1

Answer:

The answer is 6/13.

Step-by-step explanation:

u=-5m

f=1.5m

Applying mirror formula:

1/f=1/u+1/v

1/1.5=1/-5+1/v

1/v=2/3+1/5=13/15=>v=15/13m

Now object height is=2m

Let, the image height is=xm

So,x/2=(-15/13)/-5=3/13

X=3/13*2/1

∆x=6/13.
