Six artificial satellites circle a space station at a constant speed. The mass m of each satellite, distance L from the space station, and the speed v of each satellite are listed below. The satellites fire rockets that provide the force needed to maintain a circular orbit around the space station. The gravitational force is negligible.

Rank each satellite based on its acceleration. Rank from largest to smallest.

A) m= 200 kg, L= 5000 m, v= 160 m/s

B) m= 100 kg, L= 2500 m, v= 160 m/s

C) m= 400 kg, L= 2500 m, v= 80 m/s

D) m= 800 kg, L= 10000 m, v= 40 m/s

E) m= 200 kg, L= 5000 m, v= 120 m/s

F) m= 300 kg, L= 10000 m, v= 80 m/s

You are still fascinated by the process of inkjet printing, as described in the opening storyline for this chapter. you convince your father to take you to his manufacturing facility to see the machines that print expiration dates on eggs. you strike up a conversation with the technician operating the machine. he tells you that the ink drops are created using a piezoelectric crystal, acoustic waves, and the plateau-rayleigh instability, which creates uniform drops of mass m = 1.25 ✕ 10−8 g. while you don't understand the fancy words, you do recognize mass! the technician also tells you that the drops are charged to a controllable value of q and then projected vertically downward between parallel deflecting plates at a constant terminal speed of 20.0 m/s. the plates are ℓ = 2.15 cm long and have a uniform electric field of magnitude e = 6.40 ✕ 104 n/c between them. noting your interest in the process, the technician asks you, "if the position on the egg at which the drop is to be deposited requires that its deflection at the bottom end of the plates be 0.17 mm, what is the required charge on the drop (in c)? " you quickly get to work to find the answer. (neglect the force of gravity.)
