The force required to take away a flat plate of radius from the surface of the water is (surface tension of water )?
Step 1: Given data:
The radius of the flat plate is given as
The surface tension of water is given as
Step 2: Formula for calculating Force required:
We know the surface tension formula is given as:
As the force due to surface tension acts all along the circumference of the circular plate.
The length can be given as:
length = circumference of the circular plate
Hence, the formula for Force required can be given as:
Step 3: Calculating Force required to take away of plate:
Thus, putting the values given, the force required to take away of the plate can be given as:
Hence, the force required to take away a flat plate of radius from the surface of the water is
