Answer:-

Given

μ=1.5  ,R1=   ,R2=20cm(the object lies on the plane side)\mu =1.5 \ \ , R_1=\infin \ \ \ , \\R_2=-20cm (the \ object \ lies \ on \ the \ plane \ side)

we know that

1f=(μ1)(1R11R2)\frac{1}{f}=(\mu-1)(\frac{1}{R_1}-\frac{1}{R_2})

putting the values

1f=(1.51)(1120)\frac{1}{f}=(1.5-1)(\frac{1}{\infin}-\frac{1}{-20})

1f=140f=40cm\frac{1}{f}=\frac{1}{40}\\ \boxed{f=40 cm}

D=140cmD=\frac{1}{40cm} [1 meter=100cm]


D=10040D=\frac{100}{40}

power=2.5 D\boxed{power=2.5 \ D}
