A spark plug in a car has electrodes separatedby a gap of 0.025 in. To create a spark and ignite the air-fuel mixture in the engine, an electric field of 3.0 * 106V>m is requiredin the gap. (a) What potential difference must be applied to thespark plug to initiate a spark? (b) If the separation between electrodes is increased, does the required potential difference increase,decrease, or stay the same? Explain. (c) Find the potential difference for a separation of 0.050 in.

Question
A spark plug in a car has electrodes separated
by a gap of 0.025 in. To create a spark and ignite the air-fuel mixture in the engine, an electric field of 3.0 * 106
V>m is required
in the gap. (a) What potential difference must be applied to the
spark plug to initiate a spark? (b) If the separation between electrodes is increased, does the required potential difference increase,
decrease, or stay the same? Explain. (c) Find the potential difference for a separation of 0.050 in.
