A spacecraft descends vertically near the surface of Planet X. An upward thrust of 25.0 kM from its engines slows it down at a rate of 1.20 m/s2, but if an upward thrust of only 14.5 kN is applied, it speeds up at a rate of 0.80 m/s2. Part APart complete What is the direction of the acceleration of the spacecraft in the case of 25.0 kN thrust

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→∞.
