Answer:
Explanation:
Let v be the velocity acquired by electron in electric field
V q = 1/2 m v²
V is potential difference applied on charge q , m is mass of charge , v is velocity acquired
2400 x 1.6 x 10⁻¹⁹ = .5 x 9.1 x 10⁻³¹ x v²
v² = 844 x 10¹²
v = 29.05 x 10⁶ m /s
Maximum force will be exerted on moving electron when it moves perpendicular to magnetic field .
Maximum force = Bqv , where B is magnetic field , q is charge on electron and v is velocity of electron
= 1.7 x 1.6 x 10⁻¹⁹ x 29.05 x 10⁶
= 79.02 x 10⁻¹³ N .
Minimum force will be zero when electron moves along the direction of magnetic field .
(a) The maximum force on the electron due to the magnetic field will be F= 79.02 x 10⁻¹³ N .
(b) Minimum force will be zero when electron moves along the direction of magnetic field .
What is magnetic force?
Whenever a current is passes through a wire then the magnetic fields are generated around the wire and if any other charged particle comes under the influence of this magnetic field then the magnetic force is applied in the charge.
Let v be the velocity acquired by an electron in electric field
[tex]Vq=\dfrac{1}{2}mv^2[/tex]
V is potential difference applied on charge q ,
m is mass of charge ,
v is velocity acquired
2400 x 1.6 x 10⁻¹⁹ = .5 x 9.1 x 10⁻³¹ x v²
v² = 844 x 10¹²
v = 29.05 x 10⁶ m /s
Maximum force will be exerted on the moving electron when it moves perpendicular to the magnetic field .
Maximum force = Bqv , where B is magnetic field , q is charge on an electron and v is velocity of electron
F=Bqv
F= 1.7 x 1.6 x 10⁻¹⁹ x 29.05 x 10⁶
F= 79.02 x 10⁻¹³ N .
Minimum force will be zero when electron moves along the direction of magnetic field .
Hence the maximum force on the electron due to the magnetic field will be F= 79.02 x 10⁻¹³ N and the Minimum force will be zero when electron moves along the direction of magnetic field .
