Answer:
Magnetic field = 0.534 T
Explanation:
The solving is on the attach document.
When the force on some area is doubled and the area doesn't change,
then the pressure on that area has doubled.
Answer:
The z-component of the force is
Explanation:
From the question we are told that
The charge on the particle is
The magnitude of the magnetic field is 
The velocity of the particle toward the x-direction is 
The velocity of the particle toward the y-direction is

The velocity of the particle toward the z-direction is

Generally the force on this particle is mathematically represented as

So we have

substituting values
So the z-component of the force is
