10. 1/2 points| Previous Answers M14 14.6.056. My Notes A neutral solid metal sphere of radius 0.1 m is at the origin, polarized by a point charge of 8 x 10-8 C at location -0.9, o, o m. At location electric field contributed by the polarization charges on the surface of the metal sphere? (Express your answer in vector form.) 0, 0.09, 0 m, what is the charges = 1 (-388.28 arges (-388.281,38.984,0) x NC 1,38.984,0) | X N/C How do you know? The net field inside the metal sphere must be zero, so that within the sphere the field due to the charges must be equal in both magnitude and direction to the field due to the point charge The net field inside the metal sphere must be zero, so that within the sphere the field due to the charges must be equal in magnitude but opposite in direction to the field due to the point charge The net field inside the metal sphere must be reduced by a factor dependent on the metal used. We may safely assume this is copper, so that within the sphere the field due to the charges is approximately one-tenth the field due to the point charge The net field inside the metal sphere must be amplified by a factor dependent on the metal used. We may safely assume this is copper, so that within the sphere the field due to the charges is approximately ten times the field due to the point charge Additional Materials Section 14.6

Explanation / Answer

Ea = kq/ r^2 =0 as the 0.09m distance lies inside the solid sphere.
