The side of a cube of metal is measured to be ( 1.50 ± 0.05 ) cm and its mass is measured to be ( 33.2 ± 0.4) g. Determine the uncertainty in the density of the solid in kilograms per cubic meter. ( Your result must be in multiples of 10 3 kg /m 3. That means if, for example, you get a result of a 9.22x10 3 just type 9.22 in the answer box. Include proper number of digit after the decimal point and maximum of 5% of error is accepted in your answer. )

Situation 1: You have a metal cube, measuring L on each side. The metal is in electrostatic equilibrium and has a net 4. charge of Q,. The cube has a cavity within it, however-where there is no metal. The shape of this cavity is not known. Somewhere within the cavity rests a point charge, q,. Its exact location is unknown, but it is not in contact with the inner wall of the cavity At a certain point P, on the...
