Pressure difference between inside and outside of a droplet of water = 4σ/d
Bursting force = p x ?d2/4
Resisting force = σ x ?d
Bursting force = Resisting force
p x ?d2/4 = σ x ?d
or p = 4σ/d

Pressure difference inside and outside a droplet of water
Pressure inside a droplet of water is higher than the pressure outside due to the surface tension of the water.

Formula
The pressure difference can be calculated using the formula: ΔP = 2σ/d, where σ is the surface tension and d is the diameter of the droplet.

Explanation
- Inside the droplet, the water molecules are attracted to each other due to surface tension, creating a higher pressure.
- Outside the droplet, the water molecules are not being pulled in all directions, resulting in a lower pressure.
- The pressure difference is directly proportional to the surface tension and inversely proportional to the diameter of the droplet.

Correct answer
The correct answer is option B, 4σ/d, as the pressure difference is twice the surface tension divided by the diameter of the droplet.
