Neutron stars, such as the one at the center of the crab nebula, have about the same mass as our sun but a much smaller diameter. if you weigh 690 n on the earth, what would be your weight on the surface of a neutron star that has the same mass as our sun and a diameter of 17.0 km?
take the mass of the sun to be m_s = 1.99×1030 kg, the gravitational constant to be g = 6.67×10-11 n* m^2/kg^2, and the acceleration due to gravity at the earth's surface to be g = 9.810 m/s^2.
express your weight w star in newtons.

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
