and.Which
of the following statement are true?
(a) The particle could be moving in a circular orbit with
origin as centre
(b) The
particle could be moving in an elliptic orbit with origin as its focus
(c)
When the de Broglie wavelength is
, the
particle is
nearer the origin than when its value is 
(d) When the de Broglie wavelength is the particle is nearer the
origin than when its value is
Answer:
The de-Broglie
wavelength of the particle can be varying cyclically between two values
and 
if particle is moving in an
elliptical orbit with origin as its one focus. Refer Fig. 7(EP).l.
Let 
,
be
the speed of particle at A and B respectively and origin is at focus 
. If , are
the de-Broglie wavelengths associated with particle while moving at A and B
respectively. Then
and 
; Since 
From figure we note that origin is
close to P than A. Thus options (b) and (d) are true.
