Example 3 - 9702/41/MJ/18: (a) State Newton’s law of gravitation. #9702s18p41 #Lv2 #A2gForceP4
(b) A distant star is orbited by several planets. Each planet has a circular orbit with a different radius.
(i) Each planet orbits at constant speed. Explain whether the planets are in equilibrium.
(ii) The radius of the orbit of a planet is R and the orbital period is T. Data for some of the planets are given in Fig. 1.1. The relationship between R and T is given by the expression (Kepler's Law).
1. Show that the constant k is given by the expression where G is the gravitational constant and M is the mass of the star.
2. Use data from Fig. 1.1 for the three planets and the expression for k to calculate the mass M of the star
