Question

Wooden cube, density 620kg/m^3, is 0.08m tall, 0.12m wide, and 0.12m thick. It floats in a liquid with density 900kg/m^3 . A string attached to the bottom of the container prevents the cube from floating up to the surface. Find the tension in the string.

a.) Write out the Newton’s second law (net force) equation for the wooden cube.

b.) What variables in the force equation can you fill in from the given information?

c.) Substitute the given information into the force equation as appropriate and solve for the tension.
