I need to find the magnitude in N

Thank you!

**drwls**, Friday, October 28, 2011 at 12:00amLet the unknown required force be F.

F + M*g = buoyant force

= (volume)*(water density)*g

Volume = (pi/6)*D^3 = 26.52 cm^3

M = Mass = 2.23 g

That is an extremely light ball. More like a balloon.

The buoyancy force is much larger than the weight.

Solve for F
