Thor is battling the Frost Giants and he uses his hammer, Mjolnir, to zap them with lightning. Thor unleashes a bolt toward the nearest Giant. Mjolnir has an electric potential of zero and the Frost Giant has an electric potential of either +1.9 × 108 V or −1.9 × 108 V (you will decide during part 1 of the question). In order for electricity to conduct through dry air, the electric field between Thor and the Frost Giant must have a magnitude of 3.2 × 106 V A negatively charged hydroxide ion (OH¯) in the lightning bolt travels away from Thor. OH¯ ions hold a charge of -1.6 × 10-1⁹ C and they have a mass of 2.82 × 10-²6 kg. The OH- ion speeds up from rest to a velocity of 6.3 × 105 m.

The Question
Thor is battling the Frost Giants and he uses his hammer, Mjolnir, to zap them with lightning. Thor unleashes a
bolt toward the nearest Giant. Mjolnir has an electric potential of zero and the Frost Giant has an electric
potential of either +1.9 × 108 V or -1.9 × 108 V (you will decide during part 1 of the question). In order for
electricity to conduct through dry air, the electric field between Thor and the Frost Giant must have a magnitude
V
of 3.2 x 106
m
A negatively charged hydroxide ion (OH¯) in the lightning bolt travels away from Thor. OH ions hold a charge
of -1.6 × 10-¹⁹ C and they have a mass of 2.82 × 10-26 kg. The OH-ion speeds up from rest to a velocity of
6.3 × 105 m.
