an object of 5 cm is 2. The size of the image formed

by this spherical mirror will be:



(a) 20 cm (b) 0.4 cm

(c) 2.5 cm (d) 10 cm​

Answer 1

Answer:

it is 10 cm as it is a concave mirror

Explanation:

m= +2

and m= h of image / heght of object

2=x/5

x=10

Answer 2

Answer:

Size of image formed is 10 cm

Explanation:

$magnification \: = \frac{ - \: size \: of \: image}{size \: of \: object}$

$2 = \frac{ - x}{5}$

$x = 5 \times ( - 2)$

$x \: = - 10 \: cm$
