A particle with charge q and mass m is shot with K.E ''k'' into the region between two plates.If magnetic field between plates is B.How large B must be if the particle is to miss collision with the opposite plate?
Ans)To just miss the collision of the opposite plate,the paticle must move in a circular path of radius ''d'' so that,
Bqd=mv2/d
Bqd=mv------(1)
but K=1/2 mv2
K=(mv)2 /m2
2mK=(mv)2
mv=(2Km)1/2 ---------------(2)
substitutng (2) in (1)
Bqd=(2Km)1/2
B=(2Km)1/2/qd

What do you understand by "Absorption coefficient"? which is a better absorber of sound, glass or fibre glass?
Due to drift velocity of electrons and due to collision of electrons
CAPACITOR MEASUREMENTS : Many modern digital multimeters incorporate a capacitance measuring facility although this may be limited to just one or two ranges. The diagram below
A plano - convex lens of radius of curvature 2.5 m is placed on an optically plane glass plate in air medium and a parallel beam of monochromatic light is incident normal
