path of electron enter in magnetic field draw the path
Answers
Answer:
From -ive to +ive Treimal
Answer:
In a magnetic field the force is always at right angles to the motion of the electron (Fleming's left hand rule) and so the resulting path of the electron is circular ... Charged particles move in straight lines at a constant speed if projected into a magnetic field along the direction of the field.
Explanation:
Path of the electron in an electric field
We will consider next the case of an electron entering a uniform electroc field between two parallel plates (Figure 4). The potential difference between the plates is V and the plates are aligned along the x direction and the electron enters the field at right angles to the field lines:
The force on the electron is given by the equation:
F = eE = eV/d = ma
But since there is a force the electron must accelerate in the y direction and the acceleration is given by a = 2y/t2. (From the equation s = y = ut + ½ at2)
Therefore if we combine these to equations F = m2s/t2 and at right angles to then field x = vt so the equation for the path of the electron is:
eV/d = m2y/t2 = 2myv2/x2 or:
