Answer 2

Given:

• Image produced by concave mirror is six times magnified image of an object placed at 20cm.

To Find:

• Find the position of the image.

Solution:

$\sf \underline{we \: know \: that : }$

$\sf\implies \: m = \frac{ - v}{u} \\ \\ \sf\implies \: 6 = \frac{ - v}{ - 20} \\ \\ \sf \implies \: 6 = \frac{v}{20} \\ \\ \sf \implies \: v = 20 \times 60 \\ \\ \implies \sf \: v = 120$

$\sf {\underline{image \: position \: is \: 120cm \: }} \\ \sf \underline{ \: from \: mirror}$
