The gravitational force between two spherical masses, M1 = 20kg and M2 = 25kg is 8.84 * 10-7 Nt. What is the distance that separates the centers of the two masses?

The figure below shows a spherical hollow inside a lead sphere of radius R = 4.00 cm. The surface of the hollow passes through the center of the sphere and "touches" the right side of the sphere. The mass of the sphere before hollowing was M = 2.50 kg. With what gravitational force does the hollowed-out lead sphere attract a small sphere of mass m = 0.459 kg that lies at a distance d = 9.00 cm from the center of the lead sphere, on the straight line connecting the centers of the spheres and of the hollow?

Three uniform spheres of masses m₁ = 3.00 kg, m₂ = 4.00 kg, and m3 = 5.00 kg are placed at the corners of a right triangle (see figure below). Calculate the resultant gravitational force on the object of mass m₂, m2 assuming the spheres are isolated from the rest of the Universe. Î + × 10-11 N y (0, 3.00) m m (-4.00, 0) m 12 Mg F 32 Ο m2 x

The center of a 910kg satellite is 9.9x10^6 m from earths center. What is the gravitational force between the satellite and earth?

The gas-giant planet Rom (mass 5.7⨯1026 kg) goes around the star Galla (mass 2.0⨯1030 kg) in a circular orbit at a speed of 9.7⨯103 m/s. Note: G = 6.67⨯10-11 N·m2/kg2 i) How far is it from Galla to Rom (from center to center)? ii) What is the period of Rom’s orbit in Earth years?  (One Earth year is 365.25 Earth days.) iii) What is the magnitude of the force on Rom due to the Galla?

Gravitational force is F = Gm1m2/r². Set G = 1 and m1 = 1, where m2 will be a planet with 1800 times Earth's mass (so m2 = 1800) and 30 times Earth's radius (so r = 30). What will F be?

The mass of the Hubble spacecraft is 1.11 x 10ʻkg. Determine the weight of the spacecraft at the orbital altitude, which is 560km above the Earth's surface. The mass of the Earth is 5.972 x 1024kg and the radius of the Earth is 6370 km.

The earth is 150 × 10^9 m from the Sun. Earth and Sun masses are 5.97 × 10)^24 ?? and 1.99 × 10^30 ??, respectively. (a) Find the gravitational attraction between the Earth and the Sun. (b) Find the orbital period of the Earth around the Sun based on these numbers.

a planet moves in a circle around a massive star. If the planet is 7.2X10^10 m from the star, and the planet orbits the star in 67 days (=5.79X10^6 s), what is the mass of the star?

A satellite m = 500 kg orbits the earth at a distance d = 225km above the of the planetThe radius of the earth r_{e} = 638 * 10 ^ 6 * m and the gravitational constant G = 6.67 * 10 ^ - 11 * N * m ^ 2 / k * g ^ 2 and the Earth's mass m_{e} = 5.98 * 10 ^ 24 * kg What the speed of the satellite in m/s
