Question

what is nutrition and it's types?​

Answer 1

Answer:

Focal Length of Mirror = f = - 20 cm

Image Distance = v = - 60 cm

We are required to find out the object distance. Considering the mirror as Concave.

Let the object distance = u

By using Mirror Formula.

1/u + 1/v = 1/f

1/u - 1/60 = -1/20

1/u = -1/20 + 1/60

1/u = (-3 + 1)/60

u = - 60/2

\bf{u\:=-\:30\:cm}u=−30cm

Hence,

The object distance = u = -30 cm
