A mass m of 1590 kg is fixed in place on a frictionless surface at a distance L = 6.2 mm from a second mass m2 of 182 kg. Mass m2 is free to move. The surface is slowly tilted. m2 L mi =0 At what angle of inclination will the second mass begin to slide down the plane? The acceleration of gravity is 9.8 m/s and the value of the universal gravitational constant is 6.67259 10-11 N. m/kg. Three equal masses of 4 kg each are located at three corners of a square of edge length 3.5 m. Use G = 6.67259 x 10-11 Nm/kg. Find the magnitude of the gravitational field at the fourth corner due to these masses. y m 1 m Answer in units of N/kg m x
