Question

pls give correct answer its very urgent ​

Answer 1

Answer:

25 cm

Step-by-step explanation:

Given:-

u= position of object= -25cm

r = radius of curvature= 5cm

µ1 = 1

µ2 = 1.5

µ1/v - µ2/u = µ2-µ1/r

V=>1.5/v - 1/(-25) = 1.5-1/5

V=>1.5/v + 1/25 = 0.5/5 = 5/50 = 1/10

V=>1.5/v = 1/10 - 1/25

V=>1.5/v=3/50

V=50 × 1.5/ 3

V=50/2

V=25 cm
