Given that,
Mass, m = 250 g
Volume of the container, V = 50 cm³
To find,
The density of the oil.
Solution,
Density = mass/ volume
The computation for density is as follows :
So, the density of the oil is .

Answer:
n = 756.25 giga electrons
Explanation:
It is given that,
If the charge on the negative plate of the capacitor,
Let n is the number of excess electrons are on that plate. Using the quantization of charges, the total charge on the negative plate is given by :
e is the charge on electron
or
n = 756.25 giga electrons
So, there are 756.25 giga electrons are on the plate. Hence, this is the required solution.
