jack touches a negatively charged plastic rod to a mental sphere. how woll the negative charges spread throughout the sphere
When Jack touches a negatively charged plastic rod to a metal sphere, the negative charges will distribute evenly on the surface of the sphere. This is due to the principle of electrostatic induction.
Initially, the sphere is electrically neutral, meaning it has an equal number of positive and negative charges. When the negatively charged rod is brought close to the sphere, it repels the negative charges in the sphere and attracts the positive charges. This causes a redistribution of charges on the surface of the sphere.
Since the negative charges are repelled by the negatively charged rod, they will move to the far side of the sphere away from the rod, while the positive charges are attracted to the rod and accumulate on the side closer to it. This redistribution of charges creates an imbalance in the electric field, resulting in an accumulation of negative charges on one side of the sphere.
However, it is important to note that the charges will only distribute on the surface of the sphere, as metals are conductive and allow charges to move freely. Charges within the metal sphere will quickly spread and become evenly distributed on the surface due to mutual repulsion.
Overall, the negative charges will spread throughout the metal sphere, becoming evenly distributed on its surface.
