Answer:
The angular velocity is
Explanation:
From the question we are told that
The mass of each astronauts is
The initial distance between the two astronauts
Generally the radius is mathematically represented as
The initial angular velocity is
The distance between the two astronauts after the rope is pulled is
Generally the radius is mathematically represented as
Generally from the law of angular momentum conservation we have that
Here is the initial moment of inertia of the first astronauts which is equal to
the initial moment of inertia of the second astronauts So
Also is the initial angular velocity of the first astronauts which is equal to
the initial angular velocity of the second astronauts So
Here is the final moment of inertia of the first astronauts which is equal to
the final moment of inertia of the second astronauts So
Also is the final angular velocity of the first astronauts which is equal to
the final angular velocity of the second astronauts So
So

Answer:
The magnitude of the magnetic field is .
Explanation:
Given that,
Charge,
Speed of the charged particle,
The angle between the velocity of the charge and the field is 56°.
The magnitude of force,
We need to find the magnitude of the magnetic field. When a charged particle moves in the magnetic field, the magnetic force is experienced by it. The force is given by :
B is the magnetic field.
So, the magnitude of the magnetic field is . Hence, this is the required solution.
