Answer:
Image will form at distance 7.5 cm from lens
Explanation:
As we know by the lens formula
[tex]\frac{1}{d_i} + \frac{1}{d_0} = \frac{1}{f}[/tex]
here we know that
[tex]d_i = 15 cm[/tex]
[tex]f = 5 cm[/tex]
now we have
[tex]\frac{1}{15} + \frac{1}{d_i} = \frac{1}{5}[/tex]
[tex]d_i = 7.5 cm[/tex]
so here a real image will form on the other side of lens at distance 7.5 cm
