Options

A. `{:(,P,Q,R,S),((A),3,2,3,1):}`
B. `{:(,P,Q,R,S),((B),4,1,4,1):}`
C. `{:(,P,Q,R,S),((C),3,3,3,3):}`

Explanation

`F=T.4 l A=400 cm^(2), l=20 cm =0.2 m`
`8/100xx4xx2/10`
`=64/100=0.064 N~=0.06N`
(D) `h=(2T.cos theta)/(rrhog)`
`=2xx8/100xx(1xx10^(4))/(5xx10^(3)xx10)`
`=32/10xx(10^(4))/(10^(5))=32xx10^(4-7) =0.031m =3.2 cm`
