Question

Constants| Periodic Table Correct A conducting spherical shell (see the figure) has inner radius = 10.0 cm, outer radius = 15.0 cm, and has a +3.0 C point charge at the center. A charge of -3.0 C is put on the conductor(Figure 1) Part B What is the electric field inside the shell at 10.0 cm from the center? Express your answer to two significant figures and include the appropriate units. sideValue N/C Submit uest Ans Figure 1 of 1 Part C What is the electric field just outside the shell? Express your answer to two significant figures and include the appropriate units. 10.0 cm E 1 Value | N / C 5.0 cm outside E Submit uest Ans

Explanation / Answer

b)

electric field at 10cm from center = kQ/r^2

= 9*10^9*3*10^(-6)/(0.1)^2 = 18*10^5 N/C

c)

electric field outside the shell should be zero. because net charge = +3 uC -3 uC = 0

E*A = qenclose/e

here qenclose = 0

electric field E = 0
