[tex]\\ \sf\longmapsto m=\dfrac{-v}{u}[/tex]

  • v is image distance and u is object distance.

[tex]\\ \sf\longmapsto 3=\dfrac{-v}{30}[/tex]

[tex]\\ \sf\longmapsto -v=30(3)[/tex]

[tex]\\ \sf\longmapsto v=-90cm[/tex]

Answer:

Given that,

The radius of curvature, R = 15 cm

The radius of the mirror, f = -7.5 cm

We need to find the object's distance from the mirror. The mirror's formula is used to find the object distance such that,

So, the object distance is 6 cm
