Question
Part A
What is the electric field inside the metallic sphere for r < R?
Express your answer in terms of variables Q, r, and R. Combine all numerical values together into one multiplier.
E inside = ?
Part B
What is the electric field outside the metallic sphere for r > R?
Express your answer in terms of variables Q, r, and R. Combine all numerical values together into one multiplier
E ouside = ?
Part C
What is the electric potential at the surface of the metallic sphere? (r=R)
Express your answer in terms of variables Q, r, and R. Combine all numerical values together into one multiplier.
VR = ?
Part D
What is the electric potential at the center of the metallic sphere? (r=0)
Express your answer in terms of variables Q, r, and R. Combine all numerical values together into one multiplier.
.V0 = ?
A metallic sphere of radius R has charge Q placed upon it. Make ?the normal assumption that Vinfinite = 0 Part A What is the electric field inside the metallic sphere for r R? Express your answer in terms of variables Q, r, and R. Combine all numerical values together into one multiplier E ouside = ? Part C What is the electric potential at the surface of the metallic sphere? (r=R) Express your answer in terms of variables Q, r, and R. Combine all numerical values together into one multiplier. VR = ? Part D What is the electric potential at the center of the metallic sphere? (r=0) Express your answer in terms of variables Q, r, and R. Combine all numerical values together into one multiplier. .V0 = ?Explanation / Answer
Gauss's law. Electric field x closed surface area thru which the E field lines pass = enclosed charge inside that surface area / permittivity constant.
So ? = Q / V, Q=?V So flux = E field x Surface area of spere = ?V / e0
