A science group put a satellite of mass 'm' KG into a circular Earth orbit of radius 'r'. The orbital velocity it needs to remain in this orbit is v. They now put another satellite into a simmilar orbit at the same altitude. Its mass is 3 times 'm'. What orbital velocity would it need to be given? give reasons why using mathematical reasoning.

thanks, i really appreciate it
