(Answered) A crown weighed in air is found to have the same weight as

Academics

A crown weighed in air is found to have the same weight as a 5.1 kg mass, while the same crown under water seems to weigh only as much as a 4.5 kg mass.

(a) Assume that the crown is suspended by a string to a scale. Draw a free body diagram showing all the forces on the crown when the crown is suspended under water.

(b) Write Newton's 2nd Law for the forces in the vertical direction.

(d) What is the buoyant force acting on the crown in kilograms?

(e) What is the volume of water displaced?

(f) Calculate the density of the metal with which the crown is made.
