Answer:
Electrons.
Explanation:
Electricity was discovered before the discovery of electrons by J.J Thompson in 1896. Before the electron, it was thought that it is the positive ions that move through the wire and carry current—that's why today the conventional current represents the flow of positive charges.
After J.J Thompson's discovery of the electrons, it was realized that it is the electrons that actually carry the current through the conductor. But changing the direction of the conventional current didn't seem appropriate, and that's why the convention continues to be used to this day—reminding us that once it were the positive ions that were thought to carry the current.
Answer:
so the distance between two points are
Explanation:
Surface charge density of the charged plane is given as
now we have electric field due to charged planed is given as
now we have
now for the potential difference of 100 Volts we can have the relation as
(a) The magnitude of the force that the magnetic field exerts on the loop is 0.042 N.
(b) The direction of the force that the magnetic field exerts on the loop will be out of the plane.
<h3>
Magnetic force exerted on the loop</h3>
F = BIL
where;
- I is current in the loop
- L is length of the loop
emf = BVb
where;
- b is breadth of the loop
- V is velocity
- B is magnetic field
emf = 2.6 x 3 x 0.018 = 0.1404 V
Current in the loop, I = emf/R = 0.1404/0.8 = 0.18 A
<h3>Magnetic force</h3>
F = BIL
where;
F = 2.6 x 0.18 x 0.09 = 0.042 N
<h3>Direction of the force</h3>
The direction of the force that the magnetic field exerts on the loop will be out of the plane.
