A point object is placed at the centre of a glass sphere of radius 6cm and refractive index 1.5. The distance of virtual image from the surface is

A

`2 cm

B

4 cm

C

6 cm

D

12 cm

Text Solution

Verified by Experts

The correct Answer is:
C
`(mu_(2))/(v)-(mu_(1))/(v)=(mu_(2)-mu_(1))/(R )`
`or(1)/(v)-(1.5)/(-R)=(1-1.5)/(-R)`
`therefore" "v=-R=-6cm`
