Question

An object is kept at a distance of 5 cm in front of a convex mirror of focal length 10 cm.
Calculate the position and magnification of the image and state its nature.​

Answer 1

Answer:

HOPE THIS BRING A SMILE IN YOUR FACE

Explanation:

u= -5cm

f=10 cm

According to mirror formula,

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

3/10=1/v

v=10/3

v=3.3 cm

Magnification for mirror:

m= -v/u

m=-(3.3)/-5

m=3.3/5

m=33/50

m=0.66

Since the magnification is positive, the image formed is virtual and erect.
