a concave mirror produces four times magnified image of ab object placed at 10 cm in front of the mirror. find the position of image

Respuesta :

Answer:

40 cm

Explanation:

We are given that

Magnification of concave mirror, m=4

Object distance, u=-10cm

We have to find the position of image.

We know that

Magnification of concave mirror, m=[tex]-\frac{v}{u}[/tex]

Using the formula

[tex]4=-\frac{v}{-10}[/tex]

[tex]4=\frac{v}{10}[/tex]

[tex]v=4\times 10[/tex]

[tex]v=40cm[/tex]

Hence, the image is formed at distance 40 cm behind the mirror.
