Negative charge –Q is distributed uniformly over the surface of a thin spherical insulating
shell with radius R.
Part A Calculate the magnitude of the force that the shell exerts on a positive point charge q
located a distance r>R from the center of the shell (outside the shell).
Express your answer in terms of the variables q, Q, r, R, and constants π and ϵ0.
Part B Find the direction of the force that the shell exerts on a positive point charge q located a
distance r>R from the center of the shell (outside the shell).
Part C Calculate the magnitude of the force that the shell exerts on a positive point charge q
located a distance r
Express your answer in terms of the variables q, Q, r, R, and constants π and ϵ0.

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
