Question

A) A very long hollow cylinder has a 15 cm radius and has positive charge spread evenly over its surface, amounting to a linear charge density of 7 nC/m. Apply Gauss's Law to determine the electric field at r =20 cm away from the center, in units of N/C. As usual, do not include the unit in your answer.

B) A very long hollow cylinder has a 15 cm radius and has positive charge spread evenly over its surface, amounting to a linear charge density of 9 nC/m. Apply Gauss's Law to determine the electric field at r = 10 cm away from the center, in units of N/C. As usual, do not include the unit in your answer.

You will see a different number here than in the previous question because the system is using random numbers, but this is exactly the same physical setup as the previous question, just asking for the field at a different location.
