F = ma
F = pVg
p = m/V
3. The Attempt at a Solution [/B]
First i tried finding the volume of displaced water which i did by...
(50/1000) * 10 = 1000 * 10 * V ---> V = 0.00005 m^3
Next as the metal sits on the bottom its weight force minus the bouyant force contributes to the 100 g mass increase (1 N increase) in weight force on the scales. Using this we can find Mass
Buoyant force provided by 50g water = 0.5 N
Therefore weight force of metal = 1 N - 0.5 N = 0.5 N
F = ma
0.5 = m *10
m = 0.05 kg
p = m/V = 0.05 / 0.00005 m^3
p = 1000...
Which is dead wrong.
Answer says its B.) but i dont know how.
I'm sorry to ask but i urgently need the answer to this one.
Is it ok to ask for working out, or a really big hint?
Thanks in advance
