9:24 PM ooo cricket Homework: HW9 of Ch23 Point Charge and Charged Sphere A point charge q 5.8 is located at the center of a thick conducting shell of inner radius a 2.9 cm and outer radius b 4.5 cm, The conducting shell has a net charge of q2 1.8 pc- What is Ex(P), the value of the x-component of the electric field at point P located a distance 6.2 cm along thex axis from qt? N/C You currently have submissions for this question. Only 10 submission are allowed. You can make 10more submissions for this question What is EylP), the value of the y component of the electric field at point P located a distance 6.2 cm along the x axis from Q1? You currently have 0 submissions for this question. Only 10 submission are allowed. You can make 10 more submissions for this question. What is Ex(R), the value of the x-component of the electric field at point R, located a distance 1.45 cm along the y axis from q1? You currently have 0 submissions for this question. Only 10 submission are allowed. You can make 10 more submissions for this question. What is Ey(R), the value of the y-component of the electric field at point R, located a distance 145 cm along the y-axis from q1? You currently have 0 submissions for this question. Only 10 submission are allowed. You can make 10 more submissions for this question. "What is oo, the surface charge density at the outer edge of the shell?

Only 10 submission are allowed. You can make 10 more submissions for this question O For how many values of x: .5 cm x infinity) is it true that Ex -0? T 44%Explanation / Answer
Charged Shells Behave Like a Point Charge of Total Charge “Q” at the Center Once Outside the Last Shell
So,
1. Ex=K*4*10-6/0.062^2= 9.3444*106 N/C (remember net charge is considered)
2. Ey=0 as
3. Ex will be due to only q1 only so, E=K*5.8*10-6/0.0145^2=2.4772*108 N/C
4.Ey will be due to only q1 only so, E=K*5.8*10-6/0.0145^2=2.4772*108 N/C (electric field is radial so same as y)
5. The charge density on the outer shell is = +5.8 - 1.8=4, thus charge density on outer shell =4*10-6/4pi*0.045^2=1.5719**10-4 C/m2
6.The charge density on the inner shell is =5.8*10-6/4pi*0.029^2= 5.4881*10-4 C/m2
7. for more than one value
