The mass of the ion is 5.96 X 10⁻²⁵ kg
<u>Explanation:</u>
The electrical energy given to the ion Vq will be changed into kinetic energy
As the ion moves with velocity v in a magnetic field B then the magnetic Lorentz force Bqv will be balanced by centrifugal force .
So,
and
Right from these eliminating v, we can derive
On substituting the value, we get:
m = 5.96 X 10⁻²⁵ kg.
Answer:
The magnetic field is
Explanation:
From the question we are told that
The mass of the metal rod is
The current on the rod is
The distance of separation(equivalent to length of the rod ) is
The coefficient of kinetic friction is
The kinetic frictional force is
The constant speed is
Generally the magnetic force on the rod is mathematically represented as
For the rod to move with a constant velocity the magnetic force must be equal to the kinetic frictional force so
