A platinum wire ring of radius 2.5 cm floats horizontally on the surface of water. A vertical force of 0.022 N is required to detach the ring from the surface of water. Find surface tension of water.Radius (R) = 2.5cm ➝ 0.025mForce (F) = 0.022NSurface Tension of water (S)
Surface Tension of water is .
check out app! it's millions of students each other get through their schoolwork.
the formula for surface tension via these physical quantity will be-
answer: surface tension = ev^-2t^-2
s=f/l - (1)
f=e/d - (2)
from (1) & (2)
s=e/d×l - (3)
l=vt - (4)
from (3) & (4)
s=e/vt×d - (5)
