An insulating sphere of radius 13 cm has a uniform charge density throughout its volume. 13 cm 18.4 cm 7.8 cm p If the magnitude of the electric field at a distance of 7.8 cm from the center is 18700 N/C , what is the magnitude of the electric field at 18.4 cm from the center? Answer in units of N/C.
Added by Katherine S.
Step 1
- Distance from the center where the electric field is given, \( r_1 = 7.8 \) cm. - Electric field at \( r_1 \), \( E_1 = 18700 \) N/C. - Distance from the center where we need to find the electric field, \( r_2 = 18.4 \) cm. Show more…
