Let us assume that our galaxy consists of `2.5 × 10^(11)` stars each of one solar mass. How long will a star at a distance of 50,000 ly from the galactic centre take to complete one revolution ? Take the diameter of the Milky Way to be `10^5`

Two stars each of one solar mass (= `2×10^(30)` kg) are approaching each other for a head on collision. When they are a distance 109 km, their speeds are negligible. What is the speed with which they collide ? The radius of each star is `10^4` km. Assume the stars to remain undistorted until they collide. (Use the known value of
In Exercise , let us take the position of mass when the spring is unstreched as x = 0, and the direction from left to right as the positive direction of x-axis. Give x as a function of time t for the oscillating mass if at the moment we start the stopwatch (t = 0), the mass is (a) at the mean position, (b) at the maximum stretched position, and (c) at the maximum compressed position. In what way do these functions for SHM differ from each other, in frequency, in amplitude or the initial
A star 2.5 times the mass of the sun and collapsed to a size of 12 km rotates with a speed of 1.2 rev. per second. (Extremely compact stars of this kind are known as neutron stars. Certain stellar objects called pulsars belong to this category). Will an object placed on its equator remain stuck to its surface due to gravity ? (mass of the sun = `2×10^(30)`
A rocket is fired from the earth towards the sun. At what distance from the earth’s centre is the gravitational force on the rocket zero ? Mass of the sun = `2×10^(30)` kg, mass of the earth = `6×10^(24)` kg. Neglect the effect of other planets etc. (orbital radius = `1.5 × 10^(11)`
A spaceship is stationed on Mars. How much energy must be expended on the spaceship to launch it out of the solar system ? Mass of the space ship = 1000 kg; mass of the sun = `2×10^(30)` kg; mass of mars = `6.4×10^(23)` kg; radius of mars = 3395 km; radius of the orbit of mars = `2.28 ×10^8` km; G = `6.67 × 10^(–11)` N `m^2`
