How much time does it take the satellite to complete one revolution? scientists want to place a 3300 kg satellite in orbit around mars. they plan to have the satellite orbit a distance equal to 2.2 times the radius of mars above the surface of the planet. here is some information that will solve this problem:

Intro: a solid ball of radius rb has a uniform charge density ρ. part a: what is the magnitude of the electric field e(r) at a distance r> rb from the center of the ball? express your answer in terms of ρ, rb, r, and ϵ0. part b: what is the magnitude of the electric field e(r) at a distance r express your answer in terms of ρ, rb, r, and ϵ0. part c: let e(r) represent the electric field due to the charged ball throughout all of space. which of the following statements about the electric field are true? check all that apply. e(0) = 0 e(rb)=0 limr→∞e(r)=0 the maximum electric field occurs when r=0 the maximum electric field occurs when r=rb the maximum electric field occurs as r→∞.

The applied force of 3 washers will increase the applied force on the car to n.

Based on the diagram of the electric field lines around the two spherical charges, what are the signs of the left and right charge respectively?
