Four 9.5-kg spheres are located at the corners of a square of side 0.60 m. Calculate the magnitude and direction of the total gravitational force exerted on one sphere by the other three.

Solution 39P Consider a constant string tension we will have constant angular acceleration.but it also clear that we have to do some small calculation to get . 0 The string will comes off tangentially so that = 90 .top spinning is w =00,radius is half of diameter. Given data: Radius of string is r = 0.025 m Tension in the string F = 0.30 N 5 2 Moment of inertia of string is I = 3.0 ×...
