What is the force between two small charged spheres?
Hence, force between the two small charged spheres is 6×10−3 N. The charges are of same nature. Hence, force between them will be repulsive.
What is the force on the second sphere due to the first?
Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. The distance between the two spheres is 0.12 m. (b) Both the spheres attract each other with the same force. Therefore, the force on the second sphere due to the first is 0.2 N.
What is the force between two spheres weighing 20 kg each and placed 50 cm apart?
= m = 20 kg = 50 cm = 05 m.
What is the repulsion force between two protons in helium?
2.4. Since the Coulomb force goes as the inverse square, the force of repulsion between two protons in a helium nucleus is larger by about 1010 relative to the electron–proton force in an atom. Thus F p , p e l = 10 10 F e , p e l = 2.3 × 10 2 N , which would support a mass exceeding 20 kg under the earth’s gravity.
Which is heavier proton or alpha particle?
Answer. Neutrons are a bit heavier than protons, although their mass is similar. Assuming they are all at rest, the Helium nucleus has the greatest mass. … Mass of Alpha Particle = 2 proton +2 neutron :- 6.67×10^-27 kg.
How many coulombs are in helium?
So a helium nucleus, which has atomic number 2 (indicating two protons in its nucleus), would have the charge of two protons, or 3.2 × 10-19 C.
Is it possible to split helium?
Splitting a helium atom requires energy, whereas fusing two deuterium atoms into helium liberates energy. the energies you were talking about will be the same (since they involve the same number of nucleons), but the sign will be different.
Why helium should not be used in balloons?
Although it is the second most abundant element in the universe, helium cannot be manufactured, and once released into the atmosphere is lost for ever. They argue the impure helium gas used for balloons is not the same as the liquid helium used for the MRI market, and is a byproduct of supplying liquid helium.
What will happen when we run out of helium?
But unlike hydrogen, it doesn’t readily combine with other elements. So, once helium reaches the surface, it can easily escape the Earth’s gravitational pull. Other resources, such as oil and gas, may turn into pollution or be difficult to recycle.
Can we live without helium?
Without helium, space travel will still be possible, but it will be a lot more dangerous than it already is.
Is helium important for life?
Helium has no known biological role. It is non-toxic. After hydrogen, helium is the second most abundant element in the universe. It is present in all stars.
