Answer to Question 6

(i) The Event Horizon is the boundary at which light cannot cross. (ii) Use the equation Rs = 2 × 6.67 × 10^{-11 } N m^{2} kg^{-2} × 2.0 × 10^{36} kg = 2.96 × 10^{9} m (3.0 × 10^{8} m s^{-1})

(i) The Event Horizon is the boundary at which light cannot cross.

(ii) Use the equation

Rs = 2 × 6.67 × 10^{-11 } N m^{2} kg^{-2} × 2.0 × 10^{36} kg = 2.96 × 10^{9} m

(3.0 × 10^{8} m s^{-1})
