A thin convex lens made from crown glass (\mu=3/2) has a focal length f.when it is measured in two different liquids having refractive indices 4/3 ad 5/3,it has the focal lengths f_1 and f_2 respectively.The correct relation between he focal length is: [Main 2014]

Correct Answer is : f1>f and f2 becomes negative

f_2 > f and f_1 becomes negative

f_1 > f and f_2 becomes negative
