In a space research project two schemes of launchin a space probe out of the solar system are discussed: i) To lauch a probe with a velocity lare enough to escape from the solar system directly. ii)The probe is to approach one of the outer planets and with its help change its direction of motion and reach teh velocity necessary to escape from the solar system. Assume that the probe moves under the gravitational field of the sun only or the planets depending on whichever field is stronger at that point. Determine the minimum velocity and its direction relative to the earth's motion that should be given to the probe on launching according to the scheme i). [Data - velocity of earth round the sun is 30 km/s]
