What potential difference vwc between the wire and the cylinder produces an electric field of 2.00Ã104 volts per meter at a dist
ance of 1.20 centimeters from the axis of the wire? (assume that the wire and cylinder are both very long in comparison to their radii.)?
1 answer:
<span>The potential difference Vwc between the wire and the cylinder produces an electric field of 2.00Ã104 volts per meter at a distance of 1.20 centimeters from the axis of the wire is 1160 V</span>
In case of a long wire, electric field E is inversely proportional to r
Therefore E= x/r or x = E*r

Answer:
a) 95950 pascals
b) 137642.5 pascals
Explanation:
The absolute pressure (Pabs) on a fluid is:
(1)
With Pgauge the pressure due depth on the fluid and Patm the atmospheric pressure. Pgauge is equal to:
(2)
with ρ the fluid density, g the gravitational acceleration and h the depth on the fluid. Using (2) on (1) and solving for Patm:
b) Here we're going to use again (1) but now we have another value of density because it's other liquid, to know that value we should use the fact that specific gravity (S.G) for liquids is the ratio between fluid density and water density:
so:
