If a is a complex number, and a^2-a+1=0, then a^2011=?
I tried using De Moivre's theorem, Taking a=cosθ+isinθ, but didn't get anywhere, got stuck at
cos2θ+isin2θ-cosθ-isinθ+1=0. What do I do?
So I was told that a pseudo-force acts on a body when its's motion is analysed with respect to a non inertial reference frame. I'm a bit confused. Does that mean the reference frame is accelerating with respect to the body, or with respect to the earth? And why does there have to be any sort of...
You could calculate the Bohr Radius of an atom, although it only applies to single electron species(like Hydrogen)
[SIZE="5"]R=(n^2*h^2ε0)∏mZe^2
[SIZE="3"]Where,
n=orbit number
h= Plank's constant
ε0= Permittivity of Free Space
m=mass of an electron
Z= Atomic number
e= Electronic Charge
OH, I got it. Thanks. The charges would flow to the larger sphere. The inner sphere will be left with no charge. Am I right?
Also, What would happen if the two spheres aren't conductors? Would charge be redistributed at all?
Thank You!
I know that charge always lies on the surface of the conductor. If I link the two spheres with a wire, would the charge be evenly distributed between the two spheres (i.e, Q/2 and Q/2), or would all the charge flow to the outer sphere?(i.e, Q1=0 and Q2=Q)
Consider two spherical hollow conductors, charged to Q1 and Q2 coulombs respectively. What happens when one is placed within the other, and they are connected by a thin metallic wire?
I do know that if they were placed at a distance from each other, the charge is distributed in the ratio of the...
