(1) Magnetic force acting on charge moving in magnetic field is given by,
F = qvBsinθ...F ∝ v
This means that if moving charge particle has more velocity then more magnetic force will act on it.
Due to more magnetic force the direction of velocity changes rapidly and it will move on the...
According to @rumborak , The potential at points P and B may have different. But the potential difference between B & A and P & Q should be same. because the work done in the two situations is same.
But here on both sides gravitational field is same and same height will have to covered. Means same energy used.
But here on both sides have different electric field intensity means different amount of work will have to do.
As point A and Q are just outside(A and Q are very close to surface) the surface , the potentials are not same. But as we move on surface potential becomes equal.
I don't understand this phenomena.
But when you put the charges on the conductor, the charges distributed on the surface of conductor such that it acquires the same potential ( charges moves on the surface from higher potential to lower potential until whole surface becomes equipotential.)
As shown in figure, we know that at the sharp end E field is strong, and at the other end field is weak.
Inside the conductor E=0. that means V=constant. on its surface and throughout the conductor.
if we move unit positive charge from B to A or P to Q (as shown in fig.) then different amount...
Here the particle is performing circular motion due to the rotation of the earth. And for the circular motion it requires centripetal force then which force provides the necessary centripetal force. I think it is mgcos(lamda). Am i right?
So there is contradiction between metal conductor and Earth conductor.
Because it is zero in metal but not in Earth but both are good conductor.
And the property of the conductor says that charge always resides on the surface of the conductor but it is not happen in case of earth.
Then how to...
As we know, If you put charge on conductor then all the charge reside on the surface of the conductor and charge inside the conductor is zero and electric field is also zero.
Earth is also a good conductor. So the charge resides on the Earth surface?
Is there no charge inside the earth?
And...
What is the unit value of coulomb constant(k)?
I just want to know the CGS unit value of k.
In my book it is said the CGS unit value of k is 1.
By i don't know how it come.?
