Answer:

A monkey gazes in a polished spherica

ball of 10cm radius. If his eye is 20cm from the

surface, where will the image of his eye form?

Answer 2

Answer:

0.15

Explanation:

R = 10 cm

therefore f = R/2 = 10 /2 = 5 cm

u = 20 cm

use mirror formula

1/v + 1/u = 1/f

1/v + 1/20 = 1/5

1/v = 1/5 - 1/20

20-5/100 = 15/100 = 0.15 cm

so the image will be formed 0.15 cm from his eye
