Answer» Since it is 1/2 times reduced, m = 1/2 so -v/u = 1/2 similarly, 1/v + 1/u = 1/f so 1/v + 1/u = 1/-10 -v/v + -v/u = -v/-10 (multiply throughout by -v) -1 -2 = v/10 -3 = v/10 v = -30 1/2 = -v/u 1/2 = 30/u u = 60 Read more on Brainly.in - https://brainly.in/question/2120407#readmore

Answer»

Since it is 1/2 times reduced, m = 1/2

so -v/u = 1/2

similarly, 1/v + 1/u = 1/f

so 1/v + 1/u = 1/-10

-v/v + -v/u = -v/-10 (multiply throughout by -v)

-1 -2 = v/10

-3 = v/10

v = -30

1/2 = -v/u

1/2 = 30/u

u = 60
