Problem 2: Space explorers discover an mA = 8.7 x 10¹7 kg asteroid that happens to have a positive charge of qA = 4400 C. They would like to place their ms = 3.3 x 105 kg spaceship in orbit around the asteroid. Interestingly, the solar wind has given their spaceship a charge of qs -1.2 C. What speed must their spaceship have to achieve a 7500-km- diameter circular orbit? = AMA 0.gs, ms

Question
b) For the spaseship to stay in equilibrium on the circular orbit, the total force acting on the spaceship
should provide the acceleration a v²/R, directed inwards (remember that a circular motion is an accel-
erated motion, because the velocity keeps changing direction, even if its magnitude is constant). Using
Newton's second law of motion for the spaceship, Ftot = msa, where Ftot is the total force acting on the
spaceship, find the required velocity.
