Explaining the Nucleus: Positive Charges & Observations

AI Thread Summary
The scientific community initially resisted the idea of a nucleus composed entirely of positive charges due to the fundamental principle that like charges repel each other, making a stable positive nucleus seem improbable. Observations from Rutherford's alpha-particle bombardment experiments highlighted this repulsion, as the forces involved are significantly stronger than gravitational forces. The discovery of the strong nuclear force provided an explanation for how a nucleus could remain stable despite these repulsive forces, as it acts over very short distances to hold protons together. This strong force is so powerful that it necessitates a decrease in the mass of the nucleus to account for the energy involved, which also underpins the principles of nuclear energy. Understanding these concepts has been crucial for advancements in nuclear physics.

Can you tell me the answer to this question?
Why would the scientific community resist the concept of a nucleus full of positive charges and what observations helped them explain this design.

Thanks,

While considering the effect of a very powerful magnet, try to think of what would happen if you stuck the positive ends of a bunch of magnets together. Try to keep them there.

As for the second aspect, look to Rutherford and his experimentation with \alpha-particle (alpha particle) bombardment.

two like charges repel, therefore a positive nucleus seemed impossible (especially seeing as this repeling force is more than a billion million times stronger than gravity)!

Something called the strong nuclear force was discovered that helped to explain this force. The strong force holds the nucleus together and acts over and extremely short distance. The force has so much energy that Relativity shows that the mass of the nucleus most decrease to account for all of this energy. This also lays the foundation for nuclear energy.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
