Answer 1

position of the image will be in 10 centimetre far from the object

Answer 2

Answer:

$\sf \underline{Image \: position \: is \: 20cm \:}$

Solution:

Given:

• Image produced by concave mirror is two times magnified real image of an object is 5cm.

To Find:

• The position of image = ?

Explanation:

$\sf we \: know \: that :$

$\sf \implies \: m = \frac{ - v}{u} \\ \\ \implies \sf \: 2 = \frac{ - v}{ - 10} \\ \\ \sf \implies \: 2 = \frac{v}{10} \\ \\ \sf \implies \: v \: = 10 \times 2 \\ \\ \sf \implies \: v = 20$

Image position is 20cm from the mirror.

• Nature of the image is virtual and erect.
