For this task, we are meant to immerse objects (held by a mesh) in water to measure the buoyant force and deduce the object densities.

We can measure the weight force of the object, ##F_g##, and tension T and buoyancy force. We need to find the downward force on the immersed object, ##F_i##

However, I am unsure how to find the downward force ##F_i## on the immersed object. Applying Newton II in the y-direction

##T + F_j - F_i -F_g = 0## where ##T## and ##F_g## and ##B = F_j - F_i## are knowns.

And solving, ##T + F_j - F_g = F_i ##, however, how do we solve this since ##F_j## and ##F_i## are unknowns.

EDIT: I think we can solve this actually since ##F_j## can be measured using a pressure sensor in the water.

Many thanks!
