Answer:
The velocity of the proton is
Explanation:
The momentum of a particle is defined as the product of its mass by its velocity and we can calculate it using the following formula:
p=m*v Equation (1)
Where:
p: Is the momentum in kg*m/s
m: Is mass of the particle in kg
v: Is the velocity of the particle in m/s
Data known:
m= 1,6726 × 10^–27 kg : mass of the proton
p= 4.96 X 10^-19 kg.m/s.
We replace this data in the Equation (1):
Answer: The velocity of the proton is
Answer:
a) 0.21N/C
b) counterclockwise
Explanation:
a) to find the magnitude of the electric field you can use the following formula:
A: area of the ring = pi*r^2
E: electric field
Ф_B: magnetic flux
In the line integral you can assume E as constant. Furthermore, you calculate the change in the magnetic flux by taking into account that the time interval is 1.12/0.21=5.33s. By replacing in the formula you obtain:
the magnitude if the induced electric field is 0.21N/C
b) By the Lenz's law you can conclude that the current has a direction in a counterclockwise
