A black hole sits at the origin. Observer sits at a distance = 10 km along the +x axis, while object sits at the same distance along the -x axis. To the observer, light from object makes an angle theta = 3° with respect to the x axis. If the light from the object were undeflected, it would pass a distance from the black hole. The situation is shown in the diagram (not to scale). Use trigonometry to compute the impact parameter . What is the total angle of deflection of the light, called theta, in terms of $? Use Equation 15.22 multiplied by 2 to find the mass of the black hole. (The answer is between 10²⁸ and 10²⁹ kg.) -> theta theta Figure 1: The geometry of problem 6.
