Homework Statement
Suppose we are given a metallic sphere with charge Q1 and electric potential V1 and radius a. Then it is surrounded by a metallic spherical shell with charge Q2 and electric potential V2 with inner and outter radius b and c.
What is the charge and the electric potential...
Sorry this is the first time I open a thread and I might haven't been too concise.
Im asked to find the charge in the sphere knowing the inner radius = 0.15m and the outter radius = 0.2
The result I get is 2.22 exp -9 when the correct answer according to my assignment should be 1.67 exp -9 so...
Homework Statement
There's a conducting spherical shell with Q = q2 and V =100v and outter radius R
Homework Equations
V=k*Q/R
The Attempt at a Solution
First I calculate the E field using Gauss law, and I get E=q2/4*Pi*E0*r
Integrating the E field to get the potential V y...
If both spheres had a a previous charge and then were connected with the wire, both will now have the same potential put different charges, although the total charge won't change:
V1= k*Q1/R1 V2=k*Q2/R2
Now V'1=V'2 so: Q1'=V'*R1/K Q2'=V'*R2/K
and Q1 + Q2 = Q1' + Q2'
