Two neutron stars are separated by a distance of 1.0 x 1012 m. They each have a mass of 1.0 x 1030 kg and a radius of 1.0 x 105 m. They are initially at rest with respect to each other. As measured from that rest frame, how fast are they moving when (a) their separation has decreased to one-half its initial value and (b) they are about to collide

Two black holes (the remains of exploded stars), separated by a distance of 10.0 AU (1 AU = 1.50 ✕ 1011 m), attract one another with a gravitational force of 6.70 ✕ 1025 N.The combined mass of the two black holes is 5.60 ✕ 1030 kg. What is the mass of each black hole? largest value kg smallest value kg
A neutron star has a mass of 2.0 × 1030 kg (about the mass of our sun) and a radius of 5.0 × 103 m (about the height of a good-sized mountain). Suppose an object falls from rest near the surface of such a star. How fast would this object be moving after it had fallen a distance of 0.022 m? (Assume that the gravitational force is constant over the distance of the fall and that the star is not...
Chapter 4 Problem 34 A neutron star has a mass of 2.0 × 1030 kg (about the mass of our sun) and a radius of 5.0 × 103 m (about the height of a good-sized mountain). Suppose an object falls from rest near the surface of such a star. How fast would this object be moving after it had fallen a distance of 0.023 m? (Assume that the gravitational force is constant over the distance of the fall and that...
4. The equation mgy for gravitational potential energy is valid only for objects near the surface of a planet. Consider two very large objects of mass m1 and m2, such as stars or planets, whose centers are separated by the large distance r. These two large objects exert gravitational forces on each other.The gravitational potential energy is U = − Gm1m2 r where G = 6.67 × 10−11Nm2/kg2 is the gravitational constant. (a) Sketch a graph of U versus r....
A binary star system has two stars, each with the same mass as our sun, separated by 1.50×1012 m . A comet is very far away and essentially at rest. Slowly but surely, gravity pulls the comet toward the stars. Suppose the comet travels along a straight line that passes through the midpoint between the two stars. What is the speed at the comet's midpoint?
If a neutron star and a white dwarf has a total mass of 1M. If the white dwarf has a radius of 9 x 106 m and the neutron star has a radius of 11 km. i) Compare the surface gravity of both stars. ii) What is the density of the neutron star? iii) Assuming the neutron star is entirely made up of neutrons, and that the interparticle separation of a gas of density n is l = n-1/3.

Two identical particles, each having charge +q, are fixed in space and separated by a distance d. A third particle with charge -Q is free to move and lies initially at rest on the perpendicular bisector of the two fixed charges a distance x from the midpoint between those charges (see figure below). tq -Q a) Show that if х ıs small compared with d, the motion of Q is simple harmonic along the perpendicu arbi sector.
