Question

A light rigid sheet of triangular shape has a curved portion cut from it as shown in figure it floats on the surface of water some soap solution is dropped over dotted region surface tension of water and soap film are `T_(1)` & `T_(2)` respectively `T_(1)=1.5T_(2)` Mark correct option

A. The frame experiences a net force `F=(T_(1)-T_(2))R` in `yle0` direction
B. The frame experiences force `F=(T_(1)-T_(2))R` in `yle0` direction
C. The frame experiences force `(T_(1)-T_(2))(2-pi)R` in `yge0` direction
D. Resultant force on wire frame is zero

Answer 1

Correct Answer - B
`F_(y)=Txx` projected length in y direction

`F=(T_(1)-T_(2))R`
