Suppose the moon has a radius of r miles and a payload weighs p pounds at the surface of the moon (at a distance of r miles from the center of the moon). when the payload is x miles from the center of the moon (x β₯ r), the force required to overcome the gravitational attraction between the moon and the payload is given by the following relation: required force = f(x) = r2px2 poundsfor example, the amount of work done raising the payload from the surface of the moon (i. e., x = r) to an altitude of r miles above the surface of the moon (i. e., x = 2r) iswork = bf(x) dxa = 2rr2px2 dxr = rp2 mile-poundshow much work would be needed to raise the payload from the surface of the moon (i. e., x = r) to the "end of the universe"? work = mile-pounds

3. a particle with initial velocity vβ 0=(5.85Γ103m/s)j^ enters a region of uniform electric and magnetic fields. the magnetic field in the region is bβ =β(1.35t)k^. you can ignore the weight of the particle. a. calculate the magnitude of the electric field in the region if the particle is to pass through undeflected, for a particle of charge +0.640 nc.
