Questions
When an object is placed at a distance of 25cm from mirror, the magnification is m1. When object is moved 15cm farther away with respect to earlier position, the magnification becomes m2. If
detailed solution
Correct option is B
m=(ff−u) m1=(ff−u1)----(1) m2=(ff−u2)----(2) (1)/(2) ⇒4=f+40f+25⇒4f+100=f+403f=−60⇒f=−20cmP=−100f=+5DTalk to our academic expert!
