The expression for the magnitude of the electric field between two uniform conducting plates is

Here, V is potential difference between plates and d is separation between plates.
As the potential 6.00 cm from the zero volt plate (and 4.00 cm from the other) is 420 V.
Therefore,

Thus, the electric field strength between the plates is 7000 V/ m
It should be Constant speed. The line goes straight & doesn’t change within the graph.
Answer:
i'm good, hru hope ur staying safe
Explanation:
Answer b protons and electrons
The match
you need to light the match before you can light anything else.
and after the match is lit, maybe light the oil lamp first
