Please answer 1-3
A spherical capacitor is formed from two concentric spherical conducting shells separated by vacuum. The inner sphere has a radius of ra = 12.1 cm , and the outer sphere has a radius of rb = 15.1 cm . A potential difference of 120 V is applied to the capacitor.
1.
What is the capacitance of the capacitor?
Use ϵ0 = 8.85×10−12 F/m for the permittivity of free space.
2.What is the magnitude E1 of the electric field E⃗ at radius r= 12.7 cm , just outside the inner sphere?
3.What is the magnitude of E⃗ at r= 14.6 cm , just inside the outer sphere?
