Question

A concave mirror produces three times magnified (enlarged) real image of an object placed at 10 cm in front of it where is the image located?​

Answer 1

Answer:

30 cm is the answer

Explanation:

Given magnification m=3

and object distance u=10 cm and we know,

Magnification m= u/-v

−v=3×−10

v=30 cm

Thus the image is formed at distance of 30 cm.

Answer 2

Answer Crack:

To crack this problem we will use the v/u formula from Magnification.

Now the question states that the image formed is real. And by the Sign convention of mirrors we know that real images are formed in front of the mirror and are counted as -ve.

And we already have the amount of magnification that is 3.

So,

-v/10 = 3/1 (-v = image, u = object distance)

-v = 30

v = -30

Therefore the image is located 30 cm from the concave mirror.
