Finding total flux on Gaussian surface

AI Thread Summary
To find the total electric flux through a Gaussian surface inside a uniformly charged sphere, the total charge Q within the radius r must be considered, as r is less than R. The electric flux is calculated using Gauss's Law, which states that the flux is equal to the enclosed charge divided by the permittivity of free space (ε₀). Since the Gaussian surface is within the sphere, not all of Q contributes to the flux. The assumption is made that the sphere is a non-conductor, which affects the charge distribution. Understanding these concepts is crucial for correctly applying Gauss's Law in this scenario.

Homework Statement


Consider the uniformly charged sphere with radius R. Q is the total charge inside the sphere. Find the total flux passing through the Gaussian surface (spherical shell) with radius r. (r<R)

Homework Equations



I I tried solving for the Electric Flux by simply dividing the Q by Empselon Knot thought this was too simple to be right, and as I suspected it, it was wrong.

The Attempt at a Solution



I used the formula for the electric flux but using Q divided by Empselon Knot and got it wrong. Maybe I'm not getting the concepts right.

Hi phymateng! Welcome to PF! :smile:

(it's called "espilon nought" … oh, and have an epsilon: ε :wink:)

r < R, so the surface is inside the sphere, so it's not all of Q. :smile:
 
Thank you. Yes, Q is the total charge inside the sphere and they are asking me to find the total flux passing through a gaussian surface of radius r inside the sphere. Radius of sphere is R. (so r<R)
 
this solid sphere is a non conductor i assume..right?
 
it doesn't say. So I assume it isn't.
 

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 'Collision of a bullet on a rod-string system: query'

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 hanging mass'

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...
