An irregular conductor carries a surface charge density of -6.75 C/m2 at and in the vicinity of a point P on the surface. An electron is released just above P outside the conductor.
 
  What are the magnitude and direction of its acceleration the instant after it is released? (0 = 8.85  10-12 C2/N  m2, e = 1.60  10-19 C, mel = 9.11  10-31 kg)

Question 2

A neutral hollow spherical conducting shell of inner radius 1.00 cm and outer radius 3.00 cm has a +2.00-C point charge placed at its center. Find the surface charge density
  (a) on the inner surface of the shell.
 
  (b) on the outer surface of the shell.

IgA antibodies protect body surfaces exposed to outside foreign substances. IgG antibodies are found in all body fluids. IgM antibodies are the first type of antibody made in response to an infection. IgE antibody levels are often high in people with allergies. IgD antibodies are found in tissues lining the abdomen and chest.

Fatal fungal infections may be able to resist newer antifungal drugs. Globally, fungal infections are often fatal due to the lack of access to multiple antifungals, which may be required to be utilized in combination. Single antifungals may not be enough to stop a fungal infection from causing the death of a patient.
