Work required to assemble eight identical charged particles

AI Thread Summary
The work required to assemble eight identical charged particles at the corners of a cube is calculated using the formula for electric potential energy, which involves the pairwise interactions between the charges. Each pair contributes to the total work, leading to a cumulative energy that can be expressed as W = k * q^2 * Σ(1/r_ij), where r_ij is the distance between each pair of charges. Given that like charges repel, this configuration is inherently unstable, as any slight displacement of one particle will result in a net force pushing it away from the others. The stability of the configuration can be further analyzed by considering the forces acting on each particle, indicating that the system will not remain in equilibrium. Thus, the assembly of these charged particles at the corners of a cube requires significant work and results in an unstable arrangement.

1. How much work is required to assemble eight identical charged particles, each with
charge q, at the corners of a cube of side a? Explain, based on your answer, whether or
not this configuration is stable.

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...
