Question

A Convex mirror used for rear- view on an automobile has a radius of curvature of 2 m. If a bus is located at 4 m from this mirror, 8. Position of image

+1.33 m

-1.33 m

1 m

-1 m​

Answer 1

+ 1.33 is good answer . I think It is helpfull

Answer 2

Answer:

+1.33 m

Step-by-step explanation:

Radius of curvature = 2m (R)

Principal Focus = R ÷ 2

                          = 2 ÷ 2

                          = 1 m (f)

Position of bus = 4 m (u)

We know,

1/f = 1/v + 1/u

1/f - 1/u = 1/v

1/1 - 1/4 = 1/v

(4 - 1)/4 = 1/v

3/4 = 1/v

Reciprocating

4/3 = v

+1.33 m = v

Hope this helps
