Question

An object Is placed 60 cm in front of a concave spherical mirror whose focal lenght is 40cm. which of the folowing best described the image?

Options

A
Option A
B
Option B
C
Option C
D
Option D
E
Option E

Explanation

Substituting values into the formula
1/f= 1/v - 1/u
1/-40= 1/v - 1/60
1/v= 1/60 - 1/40
1/v= -1/120
v= -120 cm
Since the object is placed between f and 2f, the image formed will be real (refer to the table) and 120 cm from the mirror. Therefore option D is correct.

This option is incorrect.Substituting values into the formula

1/f= 1/v - 1/u

1/-40= 1/v - 1/60

1/v= 1/60 - 1/40

1/v= -1/120

v= -120 cm
