Answer:
1.82 T
Explanation:
Here is the complete question
Particle accelerators, such as the Large Hadron Collider, use magnetic fields to steer charged particles around a ring. Consider a proton ring with 36 identical bending magnets connected by straight segments. The protons move along a 3.5-m-long circular arc as they pass through each magnet.
Part A
What magnetic field strength is needed in each magnet to steer protons around the ring with a speed of 3.5 × 107 m/s? Assume that the field is uniform inside the magnet, zero outside.
Solution
The magnetic force on the proton equals the centripetal force on it.
So, mv²/r = Bev.
So, the magnetic field strength, B = mv/re
Since we have 36 straight circular arcs of length 3.5 m, the circumference of the circle that contains it is C = 36 × 3.5 m = 126 m. Since C = 2πr, the radius of the circle is r = C/2π = 126/2π = 20 m
So, B = mv/re where m = mass of proton = 1.67 × 10⁻²⁷ kg, v = speed of proton = 3.5 × 10⁷ m/s , e = proton charge = 1.609 × 10⁻¹⁹ C and r = 20 m
B = 1.67 × 10⁻²⁷ kg (3.5 × 10⁷ m/s)/(20 m × 1.609 × 10⁻¹⁹ C) = 0.182 × 10¹ = 1.82 T
In the absence of any other forces, the object will continue to move at 20 m/s E.
In fact, Newton's second law states that the resultant of the forces acting on an object is equal to the product between the mass and the acceleration of the object:
therefore, if there are no forces acting on the object, the term on the left is zero, and the acceleration of the object is zero as well. This means that the object will continue its motion with constant speed, and in the same direction.
