18 - Moving charge magnetism and force in magnetic field Questions Answers
In a region of space, a uniform electric field πΈβββ , uniform magnetic field π΅βββ and
uniform gravitational field πβ exist in mutually perpendicular direction. A charged particle is
moving with uniform velocity in this region. Once the particle leaves this region and another
where there is only πβ , its speed begins to decrease. How long after leaving the first region
does the velocity of particle reach the minimum value?
Answer : t=E/Bg
An electron originates at a point A lying on the axis of a straight solenoid and moves with a velocity v at an angle Ξ± to the axis. The magnetic induction of the field is B. Find the distance r from the axis to the point on the screen into which the electron strikes. The screen is oriented at right angles to the axis and is located at a distance l from the point A.
Thanks in advance sir.
