A metal sphere of radius 10 cm carries a charge of +2.0 nC uniformly distributed over its surface. What is the magnitude of the electric field due to this sphere at a point 5.0 cm outside the sphere's surface? 4.2 KN/C 400 N/C O 40 KN/C O 80 KN/C O 800 N/C Question 4 4 pts A long uniformly-charged rod creates an inwardly directed electric field at a distance d = 34.6 cm from the axis of magnitude E = 372 N/C. How much charge is in each 2.00 m length of this rod? O -4.95 nc 0 7.16 nc 0 4.95 nc 0 - 7.16 nc 0 - 143 nc O 14.3 nc
