- 5. Two objects, with masses m1 and m2, are originally a distance r apart. The gravitational force between them has a magnitude F. The second object has its mass changed to 6m2, and the distance is changed to r/3. What is the ratio between the magnitude of the new gravitational force and F?(G = 6.67 a numerical value. 10-1N.m2/kg2). You must type your answer a f60 ssfc 160 ssi 0 ssf60A) what would be the gravitational acceleration experience by mars due to the presense of the earth if it was located at half the distance to the Earth? Distance mars-earth=226.41 million km. Mars mass: 6.4*10²³ kg Earth's mass 5,9 *10²⁴kg b)should it be smaller or higher than the acutal acceleration?why?9 There is a point between the Earth and the Moon where the total gravitational field is zero. The significance of this is that returning lunar missions are able to return to Earth under the influence of the Earth's gravitational field once they pass this point. Given that the mass of Earth is 6.0 ×1024 kg, the mass of the Moon is 7.3 ×1022 kg and the radius of the Moon's orbit is 3.8 ×108 m, calculate the distance of this point from the centre of the Earth.
