Van de Graff Generator
PHXII02:ELECTROSTATIC POTENTIAL AND CAPACITANCE

359578 In case of a Van de Graaff generator, the breakdown field of air is

1 \(2 \times {10^8}\,V{m^{ - 1}}\)
2 \(3 \times {10^6}\,V{m^{ - 1}}\)
3 \(2 \times {10^{ - 8}}\,V{m^{ - 1}}\)
4 \(3 \times {10^4}\,V{m^{ - 1}}\)
PHXII02:ELECTROSTATIC POTENTIAL AND CAPACITANCE

359579 Van de Graaff generator is used to

1 Store electrical and magnetic energy
2 Build up high voltages of few million volts
3 Decelerate charged particles
4 Both 1 and 2 are correct
