Sagot :
The velocity by which charge is moving is 3m/sec if a force of 30N acts on it in a 5Tesla magnetic field.
We know very well that a moving charge can produce both magnetic field and electric field. Static charge is only able to produce electric field.
Moving charge has velocity due to that it is able to produce magnetic field.
Now, direction of charge is very important as it will decide whether force act on the charge applied by the magnetic field or not.
Now, We know very well that force exerted by magnetic field on the charge is given by(F)=qvBsinθ where
q is the amount of charge,
v is the velocity of charge
F is the amount of force
B is the amount of magnetic field and
sinθ is the angle made by the charge with the plane of magnetic field.
Since charge is moving perpendicularly to the field, therefore value of sinθ=1
Now, F=qvBsinθ
=>v=F/qvBsinθ
=>v=30/(2×5×1)
=>v=30/10
=>v=3m/sec
Hence, velocity of charge is 3m/sec.
