3D Electric Field of a Charged Sphere
Charge (q)
6.67 nC
Sphere Radius
10 cm
Measurement Distance
20 cm
Field Intensity
1.5 × 10³ N/C
Electric Field Formula:
E = q / (4πε₀r²)
Where:
E = Electric Field (N/C)
q = Charge (C)
r = Distance from center (m)
ε₀ = 8.854 × 10⁻¹² F/m
E = q / (4πε₀r²)
Where:
E = Electric Field (N/C)
q = Charge (C)
r = Distance from center (m)
ε₀ = 8.854 × 10⁻¹² F/m
Key Concepts:
- Conducting sphere: Charge on surface only
- Inside conductor: E-field is zero
- Outside: Acts like point charge at center
- Field lines are radial
