34. The orbital speed of Earth about the Sun is 3.0 × 10ª m/s and its distance from the Sun is 1.5 × 10" m. The mass of Earth is approximately 6.0 × 1024 kg and that of the Sun is 2.0 × 103º kg. What is the magnitude of the force exerted by the Sun on Earth? [Hint: Two different meth- ods are possible. Try both.]

A 230-kg object and a 530-kg object are separated by 3.90 m. (a) Find the magnitude of the net gravitational force exerted by these objects on a 65.0-kg object placed midway between them. N (b) At what position (other than an infinitely remote one) can the 65.0-kg object be placed so as to experience a net force of zero from the other two objects? m from the 530 kg mass toward the 230 kg mass
