The electric field associated with a uniformly charged hollow metallic sphere is the greatest at:

A. the center of the sphere
B. the sphere's inner surface
C. infinity
D. the sphere's outer surface

I was thinking D, the outer surface, because if you put a test charge (which is always positive) just above the surface, the electrons will be concentrated toward the outer surface. Is this correct? If not, why?

As a result of taking Allegra-D for a sinus infection, I got anxiety, nervousness, insomnia, etc. I stopped taking it almost 2 weeks ago, but I'm still feeling anxious and nervous, about nothing in particular. Is this still the side effects? Can side effects last even after you've stopped taking medicine?

My math teacher gave us a lovely home assignment to finish on our own. I'm absolutely stuck on a couple. If you could point me in the right direction on one, I could probably get the others.
Could you help me with this, please?

Given that tan a = - 4/3, a lies in the quadrant II and cos b =2/3, b lies in quadrant I. Find the exact value of sin(a+b)

I know now that
cos(a) = -3/5
sin(a) = 4/5
cos(b) = 2/3
sin(b) = sqrt(5)/3
