    Electric field problem — Changing the charge on two spheres

    Two identical conducting spheres A and B carry equal charge. They are separated by a distance much larger than their diameters. A third identical conducting sphere C is uncharged. Sphere C isfirst touched to A, then to B, and finally removed. As a result, the electrostatic force between A and B...

    Identifying forces (normal force, weight, gravity)

    When an object is resting on a surface such as the floor, there are exerted on it two forces: The normal force - force of the ground - and the weight (the force of gravity, the Earth pushing the object down), the forces drawn on the left. What are the forces on the right? Are they the same as...

    Do I exert a force on the moon?

    Hey, I was wondering. If the Earth exerts a force on the moon and the moon exerts an equal but opposite force on the Earth (Newton's third Law of motion), do I also exert a force on the moon since I also have mass and therefore, the moon would exert a force on me (equal, but opposite). Also...
