q is placed off center inside an uncharged metal sphere insulated from the ground as shown. Where is the induced charge density greatest in magnitude and what is its sign?
◦
A; negative.
◦

C; negative.
Question 2
A small metal sphere is suspended from the conducting cover of a conducting metal ice bucket by a non-conducting thread. The sphere is given a negative charge before the cover is placed on the bucket. The bucket is tilted by means of a non-conducting material so that the charged sphere touches the inside of the bucket. Which statement is correct?
◦
The negative charge remains on the metal sphere.
◦
The negative charge spreads over the outside surface of the bucket and cover.
◦
The negative charge spreads over the inside surface of the bucket and cover.
◦
The negative charge spreads equally over the inside and outside surfaces of the bucket and cover.
◦
The negative charge spreads equally over the sphere and the inside and outside surfaces of the bucket and cover.
