The required force between the two charges is approximately 3371.25 N.
The force between two point charges can be calculated using Coulomb's law, which states that:
F = k * (q₁ * q₂) / r²
where F is the force between the charges, k is the Coulomb constant, q₁ and q₂ are the magnitudes of the charges, and r is the distance between them.
In this case, we are given that one charge has a magnitude of 0.006 C and the other has a magnitude of 0.001 C, and they are separated by a distance of 4 meters. So we can substitute these values into Coulomb's law to find the force:
F = (8.99 x 10⁹ ) * [(0.006 ) * (0.001 )] / (4 )²
F = 3371.25 N
Therefore, the force between the two charges is approximately 3371.25 N.

Answer:b
Explanation:
The correct answer is: A. Smaller than an atom.
Answer:
B
Explanation:
Explanation:
Since, the given balloon contains equal volume of dry air at the same temperature and pressure therefore, moles of air filled is equal to the moles of helium gas.
Moles of air is 228363.69 moles and molar mass of air is 28.8 g/mol.
As we know that,
No. of moles of air =
228363.69 mol =
mass = 6576874.341 g
Therefore, mass left is as follows.
6576874.341 g - 913454.77 g (as 913454.77 g = mass of He)
= 5664419.57 g
Thus, we can conclude that mass left is 5664419.57 g.
Speed of light in the medium = 2.14×10⁸ ms⁻1.
The refraction of a medium = 1.4
We know that speed of light in air= 3×10⁸ m/s
The ratio of the speed of the light in air to the speed of the light in medium is defined as refractive index.
Refractive index = speed of light in air ÷ speed of light in medium
1.4 = 3×10⁸ ÷ speed of light in medium
speed of light in medium = 3×10⁸ ÷ 1.4
= 214285714.2857 km/s
Hence, the speed of light in that medium is = 214285714.2857 km/s
