## Homework Statement

## Homework Equations

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
