# A converging lens of focal length 15cm forms a virtual image at a point 10cm fro...

### Question

A converging lens of focal length 15cm forms a virtual image at a point 10cm from the lens. Calculate the distance of the object from the lens

A) 10.00cm

B) 6.00cm

C) 5.00cm

D) 1.50cm

### Explanation:

$$\frac{1}{u} + \frac{1}{v} = \frac{1}{f} = \frac{1}{15} + \frac{1}{10}$$

u = 6.00

## Dicussion (1)

• $$\frac{1}{u} + \frac{1}{v} = \frac{1}{f} = \frac{1}{15} + \frac{1}{10}$$

u = 6.00
