The metal ball serves as a conductor and creates an electric field in the space surrounding it.
The electric field causes the free electrons within the metal ball to move, creating an induced electric field that is opposite in direction to the original field. This results in a cancellation of the electric field inside the metal ball.
Yes, the electric field can be measured using a device called an electric field sensor. This allows us to quantify the strength and direction of the electric field at different points outside the metal ball.
The size of the metal ball does not affect the strength of the electric field outside, as long as the ball is large enough to be considered a point charge. However, the shape and composition of the ball can affect the distribution of the electric field.
No, the electric field outside the metal ball is not constant. It varies in strength and direction depending on the distance from the ball and the surrounding environment. It is also affected by the charge of the metal ball and any other nearby charged objects.
