The direction of the sphere's movement between two positive charges depends on the relative positions and strengths of the charges. It will move in the direction of the stronger charge, towards it if the two charges are of equal strength, or towards the resulting net charge if the two charges are of unequal strength.
The sphere moves between two positive charges because of the electrostatic force between them. Positive charges repel each other, so the sphere experiences a force in the direction away from the positive charge it is closer to and towards the positive charge it is further from.
Yes, the sphere's movement between two positive charges can be influenced by other factors such as the presence of other charges or external forces. However, the electrostatic force between the two positive charges will still be the dominant factor in determining the direction of movement.
No, the sphere's movement between two positive charges may not always be in a straight line. This is because the electrostatic force between the two charges may not be the only force acting on the sphere, and other factors such as friction or external forces may cause the sphere to deviate from a straight path.
The distance between the two positive charges does not directly affect the direction of the sphere's movement. However, as the distance between the charges decreases, the strength of the electrostatic force between them increases, which may result in a change in the direction of the sphere's movement.
