Current Attempt in Progress - Your answer is partially correct. A positively charged particle is held at the center of a spherical shell. The figure gives the magnitude E of the electric field versus radial distance r. The scale of the vertical axis is set by Es = 11.5 x 107 N/C. Approximately, what is the net charge on the shell? Assume r = 1 cm. Number 47.917 E (107 N/C) 0 E TS 21s 3rs 4rs 5rs r (cm) Units
