Application: Electrostatic precipitator. The designers of the precipitator in Problem 5.34 found that they cannot make two half-shells as needed, but they can make the precipitator of four quarter shells and connect them as shown in Figure 5.55. All other data remain the same as in Problem 5.34. Calculate:
(a) The potential inside and outside the stack.
(b) The electric field intensity inside and outside the stack.
Problem 5.34
Application: Electrostatic precipitator. An electrostatic precipitator is made by lining the interior of a smoke stack with two half-shells as shown in cross section in Figure 5.54. Assume the stack is very long and a potential difference of 100 kV is connected as shown. Calculate:
(a) The potential inside and outside the stack.
(b) The electric field intensity inside and outside the stack.
