Q.
A particle of mass m and carrying charge -q1 is moving around a charge:+q2 along a circular path of radius r.find period of revolution of charge
Q. A charged particle (mass m and charge q) moves along x−axis with velocity v0. When it passes through the origin, it enters a region having uniform electric field E=−E^j which extends up to x=d. The equation of path of electron in the region x>d is :
- y=qEdmv20(x−d)
- y=qEdmv20(d2−x)
- y=qEdmv20x
- y=qEd2mv20x
Q.
A
particle of mass m and
charge (−q)
enters the region between the two charged plates initially moving
along x-axis
with speed vx (like
particle 1 in Fig. 1.33). The length of plate is L
and an uniform electric field E
is maintained between the plates.
Show that the vertical deflection of the particle at the far edge of
the plate is qEL2/
(2m).
Compare this motion with motion of a projectile in gravitational field discussed in Section 4.10 of Class XI Textbook of Physics.
