An isolated charged conducting sphere has a radius R = 15.0 cm. At a distance of r = 18.0 cm from the center of the sphere the electric field due to the sphere has a magnitude of E = 4.90×104 N/C. (a) What is its surface charge density (in μC/m2)? μC/m2 (b) What is its capacitance (in pF)? pF (c) What If? A larger sphere of radius 29.0 cm is now added so as to be concentric with the first sphere. What is the capacitance (in pF) of the two-sphere system? pF

A disk with uniform surface charge density σ = −8.60 μC/m2 is oriented as shown in the diagram below. The field at a distance y from the center of a disk (of radius r = 0.420 m ) and along its axis is given by E = σ2 ε0(1−yy2+r2), where ε0 = 8.85×10−12 C2 /(N⋅m2) is the permittivity of free space. What is the electric potential at a location P whose coordinates are (0, 0.115 m) ? Take the electric potential at infinity to be zero. V
