Question

(a) h= (2 T cos Θ)/( r² ρ g)

Answer 1

Answer:

h=20 o3=5 . . . .. . . . . . . .

Answer 2

Check the correctness of the relation h =(2 sigma cos theta)/(r^2 dg), where h is height , sigam is surface tension, theta is angle of contact, r is radius, d is density and g in acceleration due to gravity.
