Answer #1

(a)Calculate the magnitude of the electric field at point A using the Gauss law According to the Gauss law in electrostatics,Lour owt (since A- 4TR 1C (3.10pC-1.70 pC 6.90 4(0.061 m) -1.77x10+ C/m 1.77x10 C/m2 Therefore, the required answer 1s ml.

> comment on your solution to part b)

nowhere in the question do they say the outer sphere is charge-neutral though.... in fact they tell you specifically in the problem that the outer charge carries Q2. How does your statement "the total charge of the sphere is equal to zero" reconcile with this aspect?
