the force of capillarity in plant is given by F=yrgh/2,where y is the coefficient of surface tension.Is this equation correct or not? justify your answer.

Answer 1

y has no units
r is length
h is length
g is length/time^2

so we have length^3/time^2
but for force we need
m a or mass *length/time^2

we have g in there. I suspect we need mass :)
