Finding charge of insulating sphere and conductor

AI Thread Summary
The discussion revolves around calculating the charge of an insulating sphere and the net charge on a hollow conducting sphere based on given electric field values at specific distances. The electric field at 11.5 cm from the center is 3.37x10^3 N/C inward, while at 58.6 cm, it is 1.30x10^2 N/C outward. The user attempted to find the charge using the electric field equation, but the lack of a visual configuration hindered further assistance. The need for a clear diagram is emphasized for accurate problem-solving. Understanding the electric field behavior in relation to the charges is crucial for determining the required values.

Homework Statement



For the configuration shown in the figure below, suppose that a = 6.10 cm, b = 21.6 cm, and c = 26.6 cm. Furthermore, suppose that the electric field at a point 11.5 cm from the center is 3.37x10^3 N/C radially inward, while the electric field at a point 58.6 cm from the center is 1.30x10^2 N/C radially outward.I can't copy picture so i will describe it. In the middle there is a sphere with radius a, it is an insulator. There is an outer ring around this sphere which has radius b. Than the last ring is the outermost ring with radius c. The last ring is a conductor.

(a) find the charge of the insulating sphere
(b) the net charge on the hollow conducting sphere.

Homework Equations



k_e(Coloumb constant) = 8.99 x 10^9 Nm^2/C^2
k_e(q/r^2)

The Attempt at a Solution



What i did was since the second ring there is an electric field of 3.37x10^3N/C which is given, i calculated q using the equation about. Than the innermost sphere charge should be the opposite of that.

Hi phanman, welcome to PF.

There is no configuration "shown below." Without it, we cannot help you.
 
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...
