This is due to the surface tension of water. Because of the surface tension , the drop tends to have minimum possible surface area, and the shape which is possible with minimum surface area is "spherical shape".
what is the force?
Q. Will a DC motor really produce voltage if it is spun in reverse? Answer:- It will produce voltage if you spin it forwards too. The merely difference between a DC motor
A car of mass 1.35 x 10 3 kg sits on a large piston that has a surface area of 1.23 m 2 . The large piston is linked to a small piston of area 144 cm 2 . What is the weight

Watt; W (after J. Watt, 1736-1819): The derived SI unit of power, explained as a power of 1 J acting onto a period of 1 s; thus it has units of J/s.
The force of attraction between the molecules of water is higher.
Because of surface tension, every thing in the universe wants to achieve stability,they do that by lowereing their energy.which in this case is the surface energy.a sphere offers lowest surface area yet a very large volume
