Question
A point object O is placed in front of a glass rod having spherical end of radius of curvature 30 cm. The image would be formed at
- 30 cm left
- Infinity
- 1 cm to the right
- 18 cm to the left
The correct answer is: 30 cm left
By using formula 
.
Negative sign shows that, image is obtained on the same side of object i.e. towards left.
