Answer:
The radius described the proton moving is
r=3.91mm
Explanation:
The magnetic field that moving the proton with the velocity
v=15 km/s
To find the radius combinate the magnetic field with the mass of the proton and the charge of the proton
r = mv=eB
r = mv/eB
r = 3.9mm
Answer:
The electric field is
Explanation:
From the question we are told that
The peak magnitude of the magnetic field is
Generally the peak magnitude of the electric field is mathematically represented as
Where c is the speed of light with value
So
The density of an object is the mass of the object divided by its volume.
Remember that mass of an object is the amount of matter that the object contains. The unit for mas in the standard international unit system is the kilogram (kg), which is 1000 grams; the unit of mass in the US is the pound (lb), which is 453.592 grams.
The volume of an object is the amount of space that the object occupies. The unit for volume in the standard international unit system are the cubic meter () and the liter (L); 1 cubic meter equals 1000 liters.
The density of an object is the quantity of mass of the object per unit of its volume. The unit for mas in the standard international unit system is the kilogram per cubic meter ().
Now, lets create our hypothesis:
If the mass and the volume of and object are known, then its density can be calculated dividing the object's mass by its volume.
We can conclude that the density of an object can be obtained by dividing its mass by its volume.
