Explanation:
The explanation and the FBD - free body diagram is shown in the attachment
From F = Miu(R)
The Maximum Kinetic energy of a proton is -
E(max) = 0.063 x joules.
We have a Cyclotron designed to accelerate protons.
We have to determine the Maximum Kinetic energy of Protons.
<h3>What is a Cyclotron? On what principle it works?</h3>
Cyclotron is a device used to accelerate charged particles to high energies. It works on the principle that a charged particle moving normal to a magnetic field experiences magnetic Lorentz force due to which the particle moves in a circular path. The magnetic Lorentz force is given by-
F = qvB sinθ
According to the question -
In a cyclotron the force by a magnetic field is equal to the centrifugal force.
Now, for r(max) - ( Since v = rω)
q v(max) B sin (90) =
Now -
r(max) = 0.35 m
B = 0.8 Tesla
Therefore -
v(max) =
v(max) = 0.28 x m/sec
Therefore, the Maximum kinetic energy =
E(max) =
E(max) =
E(max) = 0.063 x joules
Hence, the Maximum Kinetic energy of a proton is -
E(max) = 0.063 x joules.

Answer:
(a) σ = 3.41*10⁻7C/m^2
(b) E = 38,530.1 N/C
Explanation:
(a) In order to calculate the resulting surface charge density, you use the following formula:
(1)
σ: surface charge density
Q: charge of the satellite = 3.1 µC = 3.1*10^-6C
S: surface area of the satellite
The satellite has a spherical form, then, the area of the surface is given by:
(2)
r: radius of the satellite = d/2 = 1.7m/2 = 0.85m
You replace the equation (2) into the equation (1) and solve for the surface charge density:
The surface charge density acquired by the satellite on one orbit is 3.41*10⁻7C/m^2
(b) The electric field just outside the surface is calculate d by using the following formula:
(3)
k: Coulomb's constant = 8.98*10^9 Nm^2/C^2
R: radius of the satellite = 0.85m
The magnitude of the electric field just outside the sphere is 38,530.1 N/C
Answer:
3.46 s
Explanation:
First of all, we can calculate the acceleration of the elevator by using Newton's second law:
and the acceleration has the same direction of the net force (upward).
Now we can calculate the time takes for the elevator to cover a distance of S=15 m by using the following SUVAT equation:
where a is the acceleration and t the time. Re-arranging the equation, we find
The answer is the north pole the southern limit would be the south pole. if right please mark brainlyest
