A point object is placed at distance of 30 cm from a convex mirror of local length 30 cm. The image will form at

A

Infinity

B

Focus

C

Pole

D

`15 cm` behind the mirror

Text Solution

Verified by Experts

The correct Answer is:
D

`u=-20cm,f=+20cm, ` by using mirror formula
`(1)/(f)=(1)/(v)+(1)/(u)implies(1)/(+30)=(1)/(v)+(1)/((-30))`
`v=15 cm`, (Behind the mirror)
