- Three uniform spheres of masses m1 = 3.00 kg, m2 = 4.00 kg, and m3 = 6.50 kg are placed at the corners of a right triangle (see figure below). Calculate the resultant gravitational force on the object of mass m2, assuming the spheres are isolated from the rest of the Universe.PlzAn object is projected from the surface of the earth with a speed of 2.72×104 m/s. What is its speed when it is very far from the earth? (Neglect air resistance.)
- A particle of mass m is at rest on top of a smooth fixed sphere of radius a. Show that, if the particle is given a small displacement, it reaches the horizontal plane through the center of the sphere at a distance a((5√5+4√23)/27 from the center of the sphere5. Consider a particle of mass m constrained to move on the surface of a paraboloid whose equation (in cylindrical coordinates) is r=4az. If the particle is subject to a gravitational force, show that the frequency of small oscillations about a circular orbit 2g Va +z, with radius p = J4az, is @ =A mood of a mass m and raduis a is orbiting a planet of mass M and if radius b at a distance d (center to center) in a circular orbit. Derive an expression for the speed of the mood v in terms of M,d and the gravitational constant G.
- Consider a thin disc of radius R and consisting of a material with constant mass density (per unit of area) g. Use cylindrical coordinates, with the z-axis perpendicular to the plane of the disc, and the origin at the disc's centre. We are going to calculate the gravitational potential, and the gravitational field, in points on the z-axis only. 1. Show that the gravitational potential 4(2) set up by that disc is given by p(2) = 2mGg | dr'; make sure to explain where the factor 27 comes from, and where the factor r' in the integrand comes from. 2. Evaluate this integral. 3. Approximate p(z), both for 0 R (i.e., for points very far away). You will need the following Taylor approximation: VI+x=1++O(x²), applied in different ways.Consider a solid sphere (e.g., a planet) with mass M and radius R. The volume mass density for this planet is given by r2 p(r) = for rR where A is a constant with the units of kg/m'.Problem 9.9 Consider a planet of mass M and radius R. Assume the planet is spherical and has a constant density. By direct integration determine the gravitational field and the gravitational potential at all points inside and outside the planet. (Assume the potential is zero at infinity and there are no other bodies in the universe.)
