I'm super confused about how to approach this problem. Please help.
A ball of Styrofoam (ρ = 100 kg/m3) is totally submerged in water. The ball has a mass of 300.0 g
What is the volume of the ball?
If a string holds the ball when it’s in the water, what’s the tension in the string?

Okay, I figured out the volume, I just need help finding the tension. What should I do to find that?
Vs = 0.3kg * 1m^3/100kg = 0.003 m^3 =
Vol. of Styrofoam = Vol. of water Dis-
placed.
Mass = 0.003m^3 * 100kg/m^3 = 0.3 kg.
T = 0.3kg * 9.8N/kg = 2.94 N.
Note: Density of water = 1000kg/m^3.
