<span>Electric field is proportional to q/d^2, where q is the magnitude of the charge and d is the distance. Since all the given units are identical, we can just compare their relative magnitudes without calculating for the exact values.
A) 3/(0.4)^2 = 18.75
B) 1.5/(0.2)^2 = 37.5
C) 6/(0.4)^2 = 37.5
D) 3/(0.2)^2 = 75
Therefore, choice D has the largest electric field of all.

Answer:
it has more molecules than the burning match, which equals MORE total kinetic energy.
Explanation:
True........don't blame me if i'm wrong.<span />
The charge transported as a result of charging is 43200C .
we can note the following data from the statement :
Current (i) = 3A
Time interval (t) = 4 hrs = 14400secs
As we know ,
Current is defined as the rate of flow of the charges between two points when a potential difference is applied between them.
Mathematically , it can be written as
Current(i) = charge (q)/ time(t)
Q = i × t
= 3 × 14400
= 43200 C
By dividing the value of the current passed through the circuit by the time for which the charge is passed gives out the value of the charge passed .
