Mr. Gewanter, whose mass is 60.0 kg, is doing a physics demonstration in the front of the classroom.  How much gravitational force does he exert on 55.0 kg Martha in the front row, 1.50 m away

37. W Objects with masses of 200 kg and 500 kg are sepa- rated by 0.400 m. (a) Find the net gravitational force exerted by these objects on a 50.0-kg object placed midway between them. (b) At what position (other than infinitely remote ones) can the 50.0-kg object be placed so as to experience a net force of zero? 2151

A 175-kg object and a 475-kg object are separated by 3.30 m. (a) Find the magnitude of the net gravitational force exerted by these objects on a 61.0-kg object placed midway between them. N (b) At what position (other than an infinitely remote one) can the 61.0-kg object be placed so as to experience a net force of zero from the other two objects? m from the 475 kg mass toward the 175 kg mass

A space probe is launched from Earth headed for deep space. At a distance of 10,000 km from Earth's center, the gravitational force  on it is 900 N. What is the magnitude of the force when the probe is 30,000 km from Earth's center?

A spacecraft was designed to assess the ability of an impact to deflect the path of an asteroid. The spacecraft was launched on a rocket. At launch, the rocket has a mass of 555,000 kg and generates a force of 7.6 x 106 N. If you were to neglect the effect of gravity, what would the intial acceleration of the rocket be? Give your an answer to an appropriate number of significant figures.

Isaac Newton looks up at an apple. He is on planet earth and starts to think... which of his thoughts are true? (a) The force on the Earth is greater than the apple- because the Earth is more massive. (b) The force on the apple and the Earth are 0 because they aren't touching. (c) The force on the apple is greater than the Earth- because the Earth is more massive. (d) The force on the apple and the Earth are equal.

A 270-kg object and a 570-kg object are separated by 4.90 m. (a) Find the magnitude of the net gravitational force exerted by these objects on a 32.0-kg object placed midway between them. 1.323 × Draw a picture of the three objects, including the forces exerted on the third. N (b) At what position (other than an infinitely remote one) can the 32.0-kg object be placed so as to experience a net force of zero from the other two objects? 2.61 You appear to be assuming the answer will be a simple ratio of the masses. You must look very carefully at the equations before assuming a simple ratio holds. m from the 570 kg mass toward the 270 kg mass

What is the gravitational force acting on a person due to another person standing 3 meters away. each individual has 50kg of mass.  Help. I do not know how to start this.

Astrology, that unlikely and vague pseudoscience, makes much of the position of the planets at the moment of birth. The only known force a planet exerts on Earth is gravitational. (a) Calculate the magnitude of the gravitational force exerted on a 3.70-kg baby by a 100-kg father 0.221 m away at birth (assisting so he is close). N(b) Calculate the magnitude of the force on the baby due to Jupiter if it is at its closest to the Earth, some 6.29  1011 m away, showing it to be comparable to that of the father. The mass of Jupiter is about 1.90  1027 kg. Other objects in the room and the hospital building also exert similar gravitational forces. (Of course, there could be an unknown force acting, but scientists first need to be convinced that there is even an effect, much less that an unknown force causes it.) N
