For a charge moving perpendicularly to a magnetic field, the force experienced by the charge is given by:
where
q is the magnitude of the charge
v is the velocity
B is the magnetic field strength
In this problem,
So the force experienced by the electrons is
Answer:
The amount of gas that is to be released in the first second in other to attain an acceleration of 27.0 m/s2 is
Explanation:
From the question we are told that
The mass of the rocket is m = 6300 kg
The velocity at gas is being ejected is u = 2000 m/s
The initial acceleration desired is
The time taken for the gas to be ejected is t = 1 s
Generally this desired acceleration is mathematically represented as
Here is the rate at which gas is being ejected with respect to time
Substituting values
=>
=>
=>
=>
