radiation: high-energy charged particles emitted by the sun.
During a solar flare, the intensity of this radiation can reach
lethal levels. One proposed method of protection for
astronauts on the surface of the moon or Mars is an array of
large, electrically charged spheres placed high above areas
where people live and work. The spheres would produce a
strong electric field E to deflect the charged particles that
make up space radiation. The spheres would be similar in
construction to a Mylar balloon, with a thin, electrically
conducting layer on the outside surface on which a net
positive or negative charge would be placed. A typical sphere
might be 5 m in diameter.
Part A
What is the direction of E just outside the surface of such a sphere?
O tangent to the surface of the sphere
O perpendicular to the surface, pointing toward the sphere
O perpendicular to the surface, pointing away from the sphere
There is no electric field just outside the surface.
