Answer 2

Answer:

hi is nearly equals to 6 times height of object.

Explanation:

Given : f = 1m u = -5m

To find = v

              m

              hi

Solution :

1 / v + 1 / u = 1  f

1 / v - 1 / 5 = 1 / 1

1 / v = 1 / 1 + 1 / 5

1 / v = 5 + 1 / 5 = 6 / 5

v = 5 / 6

v = 0 . 8 3 m

m - -u/v = - ( - 5 ) / 0 . 8 3

= 5 / 0.8 3 = 6 .0 2

m is +ve

image is virtual and erect

m = h 1 / h 0

h1

= m h o

hi = 6 . 0 2 ho

hi ^ 6 ho

hi is nearly equals to 6 times height of object.
