A) The star Zog has a mass of 1.57 e30 kg. Calculate the angle by which light from a distant star is deflected at a radius of 7.61 e8 m from the center of Zog. Express answer in radians.
B) If the star Zog were to collapse into a black hole without any loss of mass, what would its Schwarzchild radius be?
C) A radio trasmitter of frequency f0 is placed at a distance 7.61 e8 m from the center of Zog. Calculate the fractional change in frequency &Delta f/fo that would be observed a long distance from the star. Use a positive (negative) to indicate an increase (decrease) in frequency.
