Answer :
Magnetic field of the given solution is 2×[tex]10^{-19} N[/tex]
Similar to how an electric field surrounds an electric charge, the magnetic field is the area around a magnet which exert a magnetic force and it is a result of moving electric charges. Magnetic field lines are a visual tool used to represent magnetic fields.
By using the formula of motional emf i.e E = Blv
here, E = Induced emf
B = magnetic field
l = length of the conductor
v = velocity
The magnetic field using the formula
f = qv × B
The velocity of electrons and lod is same
by using above equations we get f = qvBsinθ
by putting the given values we get
f = (1.6022×[tex]10^{-19}[/tex]) (5) (0.25t)
f = 2×[tex]10^{-19} N[/tex]
Magnetic field of the given solution is 2×[tex]10^{-19} N[/tex]
