<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.

b)
Explanation:
From the question we are told that
Diameter of hole
Depth of hole
Diameter of tank
Generally the equation for pressure is mathematically given as
Where
Generally the level at which the water level will initially drop if the water is not replenished is mathematically given by
Therefore the level at which the water level will initially drop if the water is not replenished
