If the electron goes a distance d, the amount of work done on it by the magnetic field is zero.
Because magnetic force acts perpendicular to the direction of motion, it has no effect on any moving charge particle. As a result, speed won't change.
<h3>What is Magnetic field?</h3>
- The magnetic influence on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field.
- A force perpendicular to the charge's own velocity and the magnetic field acts on it when the charge is travelling through a magnetic field.
- A compass, a motor, the magnets that hold items in refrigerators, railroad tracks, and modern roller coasters are examples of devices that use magnetic force.
- A magnetic field is created by all moving charges, and any charges that move across its regions are subject to a force.

Answer:
Both rod have the same tensile stress
Explanation:
Given information,
The weight first rod, 
= 1000 N
The length of first rod, 
= 2.0 m
The weight second rod, 
= 500 N
The length of second rod, 
= 1.0 m
The equation of tensile stress, σ = 
where
σ = tensile stress (N/
or Pa)
F = Force (N)
A = Area (N/ or Pa)
so
σ1 = 
, A = 2πl
= 
= 
N/
now calculate σ2
σ2 = 
= 
= N/
σ1/σ2 = /
σ1/σ2 = 1
σ1 = σ2
Hence, the tensile stress of first and second rod are the same.
