F3 F1 unit F2 The diagram above represents an object held in static equilibrium by three cables. If F1 = 470 Newtons and F2 = 570 Newtons, what should the magnitude of F3 be? number unit F1 is at a height 1.7 meters above the center of mass, while F2 goes directly through the center of mass. How far up should F3 be from the middle of the object in order to balance the torque? number

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
