Question

In the figure a nonconducting spherical shell of inner radius a = 2.15 cm and outer radius b = 2.51 cm has (within its thickness) a positive volume charge density $\rho$ = A/r, where A is a constant and r is the distance from the center of the shell. In addition, a small ball of charge q = 47.2 fC is located at that center. What value should A have if the electric field in the shell ($a \leq r \leq b$) is to be uniform?

Name: In the figure a nonconducting spherical shell of inner radius a = 2.15 cm and outer radius b = 2.51 cm has (within its thickness) a positive volume charge density ρ = A/r, where A is a constant and r is the distance from the center of the shell. In addition, a small ball of charge q = 47.2 fC is located at that center. What value should A have if the electric field in the shell (a ≤ r ≤ b) is to be uniform?

In the figure a nonconducting spherical shell of inner radius a=2.15cm and outer radius b=2.51cm has (within its thickness) a positive volume charge density ho =(A)/(r), where A is a constant and r is the distance from the center of the shell. In addition, a small ball of charge q=47.2fC is located at that center. What value should A have if the electric field in the shell (a<=r<=b) is to be uniform? In the figure a nonconducting spherical shell of inner radius a=2.15 cm and outer radius b =2.51 cm has(within its thickness) a positive volume charge density p = A/r,where A is a constant and r is the distance from the center of the shell.In addition,a smal ball of charge q = 47.2 fC is located at that center.What value should A have if the electric field in the shell (a r b) is to be uniform?
