The answer to this is easy once you look at the units for Joules. 1 Joule = 1 N.m (Newton.meter). The 'Newton' is the units of force that we are trying to find, and we know the meters is 2, from the question. So you have an 8Joule or 8N.m energy difference over 2 meters.
well if we know the meters, then the real question is written as:
8N.m = ?N x 2m
so just solve for N;
N = 8N.m / 2m = 4
So F = 4N
Answer:
The magnitude of minimum potential difference is 1800 V
Explanation:
Given:
Electric field 
Gap between electrodes
m
For finding the minimum potential difference,


V
Therefore, the magnitude of minimum potential difference is 1800 V
Answer:
formula
speed = distance / time
distance = speed x time
distance = 346 x 5
distance = 1730 m
The distance of the lightening strike would be 1730 m or 1.7 km
