Question

an object kept at a distance of 5cm in iron of convex mirror of a focal length 10 cm calculate the position and magnification of the image and find its nature

Answer 1

Given data:-

u= -5cm
f= -10cm

Position:-


1/f= 1/v+1/u
1/-10= 1/v+1/-5
-1/10=1/v-1/5
-1/10+1/5=1/v
-1+2/10=1/v
1/10=1/v

v=10cm

m=-v/u
=-10/-5
=2cm

Nature of image:-

Virtual and erect

Hope it helps
