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

A

infinity

B

pole

C

focus

D

15 cm behined the mirror

Text Solution

Verified by Experts

The correct Answer is:
D
(d) Given,u=-30cm and f=30 cm
`(1)/(v)+(1)/(30)=(1)/(30)rArr(1)/(v)=(1)/(30)+(1)/(30)=(1)/(15)`
Distance from the mirror,v=+15 cm
