a shell, spherical conductor C has an internal radius of 40 cm and an external radius of 60 cm. In the center of the shell, there is a conductive sphere S of 20 cm in radius. The r axis is a radial axis whose origin coincides with the center of the sphere

 

a) Determine qS knowing that: Er = -110 N/C in r = 26 cm and Er =120 N/C in r = 64 cm Use a period, not a comma. Unit: nC Dec.: 3 b) Determine qC knowing that: Er = -110 N/C in r = 26 cm and Er =120 N/C in r = 64 cm Use a period, not a comma. Unit: nC Dec.: 3

 

Une coquille conductrice sphérique \( \mathbf{C} \) possède un rayon interne de \( 40 \mathrm{~cm} \) et un rayon externe de \( 60 \mathrm{~cm} \) (schéma cicontre). Au centre de la coquille se trouve une sphère conductrice \( \mathbf{S} \) de \( 20 \mathrm{~cm} \) de rayon. L'axe \( r \) est un axe radial dont l'origine coïncide avec le centre de la sphère.
