A) 2T L
B) 4T L
C) 8T L
D) 16 T L
Correct Answer: C
Solution :
Since the wire frame is dipped in liquid,therefore its membrane has two free surfaces.Total length of square wire frame in contact ofmembrane = 2 \[\times \] perimeter of square \[=2\times 4L=8L\] Hence, force acting on a frame\[F=T\,l=T\times 8L=8T\,L\]You need to login to perform this action.
