Answer:
Explanation:
The volume of contaminated water
= cross sectional area x height of water level
3.14 x 9 x 9 x 7.5 ft³
= 1907.55 ft³
mass = density x volume
= 1907.55 x 63.5 lbs
m = 121129.425 lbs
This mass has to be raised to the height of 8 ft before evacuation .
There is a rise of centre of mass of
8 - 7.5/2 ft
h = 4.25 ft
Energy required
= mgh
= 121129.425 x 32 x 4.25
= 16473601.8 unit.

Explanation:
From the question we are told that:
The Electric field of strength direction =Right
The Velocity of The First Electron=V_0
The Velocity of The Second Electron=V_0
Therefore
![V_{e1}=V_{e2}](https://tex.z-dn.net/?f=V_%7Be1%7D%3DV_%7Be2%7D)
Generally, the equation for the Horizontal Displacement of electron is mathematically given by
![D=\frac{at^2}{2}](https://tex.z-dn.net/?f=D%3D%5Cfrac%7Bat%5E2%7D%7B2%7D)
Where
Acceleration is given as
![a=\frac{V_o}{2d}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7BV_o%7D%7B2d%7D)
And
Time
![T=\frac{d}{v_0}](https://tex.z-dn.net/?f=T%3D%5Cfrac%7Bd%7D%7Bv_0%7D)
Therefore horizontal displacement towards the left is
![D_l=\frac{(\frac{V_o}{2d})(\frac{d}{v_0})^2}{2}](https://tex.z-dn.net/?f=D_l%3D%5Cfrac%7B%28%5Cfrac%7BV_o%7D%7B2d%7D%29%28%5Cfrac%7Bd%7D%7Bv_0%7D%29%5E2%7D%7B2%7D)
