Explanation:
The potential produces by a point charge is given by:
Here, k is the Coulomb constant, q is the signed magnitude of the point charge and r is the distance between the charge and the point at which the electric potential is measured. Solving for q:
Answer:
Rise in level of fluid is 0.11 m
Rise in level of fluid in case of mercury is 0.728 cm or 7.28 mm
Solution:
As per the question:
Density of oil,
Change in Pressure in the tank,
Density of the mercury,
Now,
To calculate the rise in the level of fluid inside the manometer:
We know that:
1 mmHg = 133.332 Pa
Thus
Also,
where
g = acceleration due to gravity
h = height of the fluid level
h = 0.11 m
Now, if mercury is used:
h = 0.00728 m = 7.28 mm
