AI Thread Summary
When two charged iron balls with charge Q each touch, they effectively combine their charges, resulting in a total charge of 2Q. This scenario assumes the balls are identical spheres, maintaining symmetry in charge distribution. The volume of the combined system will be double that of one individual ball, but the charge density will remain consistent across the new volume. The discussion emphasizes the importance of symmetry in understanding the behavior of the charges. Overall, touching the balls allows for charge redistribution while maintaining their physical properties.

Hey!
This isn't a question from a book. Its something that I am not 100% sure about.

The question
What happens if two iron balls with charge Q each, touch each other?

My thought
These balls can be seen as a separate ball with a charge of 2Q. ( I am not so sure what to say about the volume of that iron ball though)

Two iron balls of the same size? What does symmetry say?

Lets say that they are identical spheres.
 
What do you expect?
 
I wrote my thoughts above. :) Or do you mean the volume? The volume will be 2*the volume of one metall ball. The charge/cm^3 must be the same I guess.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging 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...
