<h2>The magnitude of the magnetic is 0.145 T</h2>Explanation:
Given :
Speed of proton
Mass of proton Kg
The force on the proton in magnetic field is given by,
But (∵ Force is perpendicular to the velocity so
)
When particle enter in magnetic field at the angle of 90° so particle moves in circle
So force is given by,
Where radius but in our case 0.23 m,
C
By comparing above two equation,
T
Answer:
55.8 m/s
Explanation:
= Actual frequency of sound emitted by car
= frequency observed when the car moves =
= Speed of sound = 343 m/s
= Speed of car
Frequency observed is given as
