Answer 2

Answer:

Explanation:

Final Answer : Option B:

Understanding :

1) Forces will be due to Pressure ( Both atmospheric and Change in height of liquid) and Surface Tension.

2) Net Force = Force (Pressure) - Surface Tension Force

(- ) sign since both are opposite to each other.

3) Since, Pressure will change due to height,

so that we will write Pressure in terms of distance and integrate it to height h in liquid.

Formula :

1) Surface Tension Force = T ( 2R)
