Question

The focal length of a converging mirror is 10cm. If the object of height 5cm is placed 15cm from the mirror, then find the image distance, nature and size of the image​

Answer 1

Answer:

f=-10

u=-15

h=5

1/v=1/f -1/u

=-1/10 - (-1/15)

=-3+2/30

=-1/30

v=-30cm

Answer 2

Answer:

Given, U=-15 cm(distance of object is alwys -ve)

h=5cm

f=-10(focal lenght of concave mirror or converging mirror is -ve)

v=?

using lense fomula:

1/v+1/u=1/f

Step-by-step explanation:

1/v+1/u=1/f

1/v+(1/-15)=1/-10

1/v=1/-10+1/15

1/v=-1/30

v=-30cm

so,the distance or position of image is -30cm

Nature:real and inverted

Size:

m=h'/h=-v/u

h'/h=-v/u

h'/5=-(-30)/-10

h'=-15cm

so, the size of image is (-15cm) diminished image.
