Answer:
focal length of converging lens=20
object distance=-60. (object distance always be-ve)
by using lens formula
1/f=1/v -1/u
=> 1/20 = 1/v - (1/-60)
=>1/20 = 1/v + (1/60)
=>1/20 - 1/60 = 1/v
=>3-1/60 =1/v
=>2/60. = 1/v
=> 30= v
Explanation:
The image Will be real
The image Will be inverted
The image Will be formed between f1 and f2
