Normal Force is equal to the force acting on the surface. which is in case Y-Component of G.and it must be perpendicular to the surface. so when we have an angle over here. you need to get the Y-component of the FG(Force of Gravity). which is equal to the normal force. if you don't have an...
B. because on the outside. there is more fluid. therefore. more weight that is the fluid putting on the glass. but on the inside. less fluid and the same surface are touching the tube! so it would be easier for the fluid to rise inside the tube. this question is really common sense! i never did...
when i do the geometry i get an unreasonable answer of
cosθ= adjacent/hyp
cos10= 50/ hyp
hyp=50/ cos10
hyp = 49.24 N.
is that correct?
i did it wrong last time. i belive this is correct. answer is reasonable this time!
here is how the problem looks.
