Question

focal length of one convex mirror is 3m and object distance 5m ,then find the image distance

Answer 1

1/f =1/v+1/u laga do ajaega ans u=-5m and v=?nikalna hhh f=3m= 1/3+1/5=1/v=2/15

Answer 2

Given :
focal length of convex mirror=f=-3m
Object distance= -u = -5m
v=?
Mirror formula:
1/f=1/v+1/u
1/v=1/f-1/u
=-1/3+1/5
=-3+5/15
1/v=2/15
v=15/2=7.5m
