If a circular accretion disk around a 1.4 M. neutron star has a radius of 1.00 x 105 km as measured from the center of the neutron star to the edge of the disk, what is the orbital velocity (in km/s) of a gas particle located at its outer edge? (The mass of the Sun is GM 1.99 x 10° kg. Hint: Use the circular orbit velocity formula, V. = : make sure to express quantities in units of meters, kilograms, and seconds.) km/s
