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".
A medium is characterised by relative permittivity ε r =45 and relative permeability μ r =5. Determine the speed of e-m wave in the refractive and medium index of the medium.

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
