In the above problem,If the size of the image formed at the positions are`6cm and 3cm` then the height of the object is

A

`4.2cm`

B

`4.5cm`

C

`5cm`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A

From displacement method
`h=sqrt(h_(1)xxh_(2)) implies h= sqrt(6xx3) implies h=sqrt18=4.2"cm"`
