A straw `6 cm` long floats on water. The water film on one side has surface tension of `50 dyn//cm`. On the other slide, camphor reduces the surface tension to `40 dyn//cm`. The resultant force acting on the straw is

A staw 6 cm long floats an water . The water film on one side has surface tension of 50 dyne / cm on the other side camphor reduces the surface tension to 40 dyne/cm . The resultant force acting on the straw is 12 K dyne . find K
