(a) Find the magnitude of the net gravitational force exerted by these objects on a 58.0-kg object placed midway between them
________N

(b) At what position (other than an infinitely remote one) can the 58.0-kg object be placed so as to experience a net force of zero from the other two objects?
_________m from the 585 kg mass toward the 285 kg mass
