Question

a concave mirror produces three times real image of an object placed at 10 cm in front of it. where 8s the image located?​

Answer 1

Answer:

 magnification(m) = -3 (as image is real)

object distance(u)  = -10cm

image distance (v)=?

we know that   m= -v/u

-3 =  -v /-10

-3 = v/10

 

v =-3 * 10

v = - 30 cm

thus the image is 30 cm away from the concave mirror

hope it helps!!!!!
