The resultant of two vectors a and b is inclined at 45degree to either of them. what is the magnitude of the resultant?

Jupiter has a mass 318 times that of earth and its radius is 11.2 times that of earth's radius. estimate the escape velocity of a body from jupiter's surface given that the escape velocity from the earth's surface is 11.2km/s. do no give links.
