= A particle with charge 9₁ = +4.7 μC is located at (x=0,y=0). A second particle with charge 92 is located at (x=0,y=4.00 cm), and a third charge 93 = +5.4 µC is located at (x=3.00 cm,y=0). (a) In your notebook, draw a diagram of the three-charge system showing the location of the charges. (b) Calculate the potential energy of this three-charge system. PE = J -8 μC

A rocket in space consumes fuel and oxidizer at the rate of 2.15 x 104 kg/s with an exhaust speed of 3.30 x 10 m/s. (a) Find the thrust (in N) produced by the rocket's engine. (b) Find the acceleration (in m/s2) of the rocket at liftoff from Earth's surface, if its initial mass was 3.00 x 10° kg. (Enter the magnitude.) m/s?

*Chapter 22, Problem 030 GO The figure shows two concentric rings, of radiiR and R' = 2.34R, that lie on the same plane. Point P lies on the central z axis, at distance D = 3.15R from the center of the rings. The smaller ring has uniformly distributed charge Q = 6.84 x 10° °C. What is the uniformly distributed charge on the larger ring if the net electric field at P is zero? Number 1 Units
