Objects with masses of 235 kg and a 535 kg are separated by 0.330 m. (a) find the net gravitational force exerted by these objects on a 34.0-kg object placed midway between them. magnitude n direction (b) at what position (other than infinitely remote ones) can the 34.0-kg object be placed so as to experience a net force of zero? m from the 535-kg mass
