Question

1)An electron (mass=9.1 x 10-31, charge = -1.6 x 10-19C) experiences no deflection if subjected to
an electric field of 3.2 x 105 V/m and a magnetic field of 2.010-'Wb/m². Both the fields are normal
to the path of electron and to each other. If the electric field is removed, then the electron will revolve in
an orbit of radius:
(1) 45 m
(2) 4.5 m
(3) 0.45 m
(4) 0.045. m
2)A charged particle inoves in a magnetic field B = 101 with initial velocity ū = 5i + 4%. The path of the
particle will be
(1) straight line (2) circle
(3) helical
(4) none
3)A electron experiences a force (4.0 i +3.0j)10-13 N in a uniform magnetic field when its velocity is
2.5kx107 ms. When the velocity is redirected and beco
ms, the magnetic
force of the electron is zero. The magnetic field vector B is:
1) - 0.075i +0.19 (2) 0.1+0.075) (3) 0.075 -0.13+k (4) 0.075 -0.1)​
