Answer 1

Answer:

As the object is between pole and focus of a concave mirror, the image is formed back of the mirror and it is magnified.

The mage is virtual, erect and magnified.

Here,

u = -10

f = -20

Mirror formula:

1/v + 1/u = 1/f

1/v - 1/10 = -1/20

1/v = 1/10 - 1/20 = 1/20

1/v = 1/20

v = 20cm

So the image is formed at a distance 20cm back of the mirror.

Magnification (m) = -v/u = -20/-10 = 2

So the image size is twice the size of the object and image is erect.
