Question

hello

this is Electromagnetics class

i want the answer for all of this questions please

with clear written and clear step and clear picture please

thank you

A partial cylindrical surface is defined by p surface and is given by e.-0.C/m. that -4, b=3m, -45, d,-90. and h-2m. This description is for problems 11 through 15. An image of b,sse,and-hszsh.Asurface charge density exists on this The overall task of this problem is to find the electric field at the origin, Assume the surface is shown on the right 11) Which of the following is the correct position vector to the surface charge for this problem? a) r' 0 (bh) b) r'1+ c) r'-3p+2 d) r l e) None of these 12) Which of the followine is the correct distance vector between the source P. (-) points and the origin for this problem? a) R-3p-2 (b.4.-) b) R-lp-l c) R 1+z d) None of these e) R-1-z 13) What is the ds' for this geometry? ds' = p'dp'do a) b) None of these c) ds'=r'dr'de ds' 3dp'dz d) ds' 3dd'dz' e) 14) What is the electric fieldE at the origin'? [(5+1)+](e) a) b) [(5.1)2-5](e) c) d) None of these [(-1)2+]2) e) 15) If the surface charge density on the partial cylinder is surrounded by a sphere (centered on the origin) of radius 10b, what is the net electric flux through this sphere? a) 6r C b) 12r C c) None of these d) C e) 2r C 16) A PEC sphere of radius 8m is centered on the origin in a medium for which & 4s,.If the electric field for r 2 8m is E F/(256,), what is the surface charge density on the sphere? a) 0 C/m b) (1/16) C/m c) None of the others d (1/64) C/m e (1/32) C/m
