The conducting shell is uniformly charged with a linear charge density A2 3.5 uc/m. 1) What is Ex(P), the electric field at point P, located at (x,y) 8.2 cm, 0 cm) NIC Submit 2) What is EV(P he electric field at point P, located at (x,y 8.2 cm, 0 cm) NIC Submit Optional interactive Example Sph eres Interactive Example Cylinder Standard Exercise Point Charge and Charged Sphere Standard Exercise Line Charge and Charged Cylindrical Shell Standard Exercise Line Charge and Charged Cylindrical Shell Standard Exercise Infinite Charged Sheet and Infinite Conducting SlabExplanation / Answer
1) |E| = (lamda1 + lamda2)/(2*pi*epsilon*r)
= 2*k*(lamda1 + lamda2)/r
= 2*9*10^9*(-7.2 + 3.5)*10^-6/0.082
= 8.12*10^5 N/c (towards +x axis)
so,
Ex(P) = 8.12*10^5 N/c <<<<<<<<<<-----------Answer
2) Ey(P) = 0
3) |E| = lamda1/(2*pi*epsilon*r)
= 2*k*lamda1/r
= 2*9*10^9*(-7.2)*10^-6/0.019
= 6.82*10^6 N/c (towards the center)
so,
Ex(R) = -E*sin(30)
= -6.82*10^6*sin(30)
= -3.41*10^6 N/c <<<<<<<<<<---------------Answer
4) Ey(R) = E*cos(30)
= 6.82*10^6*cos(30)
= 5.91*10^6 N/c <<<<<<<<<<-----------Answer
