Answer:
The flux through the surface of the cube is
Solution:
As per the question:
Edge of the cube, a = 8.0 cm =
Volume Charge density,
Now,
To calculate the electric flux:
(1)
where
= electric flux
= permittivity of free space
Volume Charge density for the given case is given by the formula:
(2)
Volume of cube,
Thus
Thus from eqn (2), the total charge is given by:
Now, substitute the value of 'q' in eqn (1):
Explanation:
- A substance will floats if it is having lower density than the density of the liquid in which it is placed.
- A substance will sink if it is having density greater than the density of the liquid in which it is kept.
Density of corn syrup =
1) Density of gasoline =
Density of the gasoline is less than the the density of corn syrup which means it will float in corn syrup.
2) Density of water =
Density of the water is less than the the density of corn syrup which means it will float in corn syrup.
3) Density of honey =
Density of the gasoline is more than the the density of corn syrup which means it will sink in corn syrup.
4) Density of titanium =
Density of the titanium is more than the the density of corn syrup which means it will sink in corn syrup.
