1)
The excess charge on a conductor will move
a) to the center if the charge is positive and to the exteriorsurface if it's negative
b) to the center if the charge is negative and to the exteriorsurface if it's positive
c) to the exterior surface if the charge is positiveor negative
d) to the center if the charge is positive or negative
e) to a situation where the charge is uniformly distributed
2)
If you are finding the force between an sphere with a uniformcharge distributionand a point charge, you can use Coulomb's Law, but in this case the"r" willrepresent
a) the distance between the point charge and the center of thesphere
b) the distance between the point charge and the closest part ofthe sphere
c) the distance between the point charge and the farthest partof the sphere
d) none of the above is correct. Coulomb's Law cannot beapplied.
3)
If you double the distance between two charged objects, theelectrostaticforce between them
a) goes down by a factor of 2
b) goes down by a factor of 4
c) goes up by a factor of 2
d) goes up by a factor of 4
e) none of the above is correct
4)
The units for electrical flux are
a) N/C
b) N/m2
c) N.m2/C
d) N /m2 C
e) none of the above is true. Flux is unitless.
5)
Gauss's Law gives the amount of electrical flux that passesthrough a surface thatsurrounds an electrical charge. Gauss's Law works, only ifthat surface is
a) a cube
b) a sphere
c) a cylinder
d) none of the above is true. The surface can be anyclosed shape.
