To find the maximum potential difference created by the Van de Graaff generator, we need to use the relationship between the electric field (dielectric strength) and the potential difference. Here are the steps to solve the problem: 1. **Identify the given values:** - Dielectric strength of air, \( E = 3 \times 10^6 \, \text{V/m} \) - Radius of the hollow sphere, \( R = 0.5 \, \text{m} \) 2. **Use the formula that relates the electric field and the potential difference:** \[ ...
