Two bodies A, B of masses m1, m2 are knotted to a mass-less string at different points rotated along concentric circles in horizontal plane. The distances of A, B from common centre are 50cm, 1m. If the tensions in the string between centre to A and A to B are in the ratio 5:4, then the ratio of m1 to m2 is:

Check Your Understanding Galaxies are not single objects. How does the gravitiational force of one galaxy exerted on the “closer” stars of the other galaxy compare to those farther away? What effect would this have on the shape of the galaxies themselves?
Check Your Understanding Consider the density required to make Earth a black hole compared to that required for the Sun. What conclusion can you draw from this comparison abut what would be required to create a black hole? Would you expect the Universe to have many black holes with small mass?
In a particle accelerator, a proton has mass 1.6710-27kg and an initial speed of 2.00105m/s . It moves in a straight line, and its speed increases to 9.00105m/s in a distance of 10.0 cm. Assume that the acceleration Is constant. Find the magnitude of the force exerted on the proton.

A binary star system consists of two stars that revolve about their centre of mass in circularorbits. Suppose that the system is observed edge on. Because of Doppler shift the spectral linesfrom the two stars (known as a spectroscopic binary system) are observed to shift periodicallyabout a mean to shorter and longer wavelengths as each star moves towards or away from theobserver. a) Explain how the orbital period Porb and components of velocity along the line of sight v0,1and v0,2, for each star, can be found from the observed spectral lines.b) Explain how the velocities of the two stars, v1 and v2, and the angular velocity of the starsω can be determined.
