Q)
(chatquestion)...3-
r dB
E(r)
for r < a
Electric field at a point lie inside the cylinder
%3D
2 dt
=> Electric field at B increases as r
a? dB
E(r)
for r> a
Electric field at a point lie outside the cylinder
2r dt
Electric field at A decreases as
Both the electric fields are in clockwise direction.
.. Electric field at A as well as at B is directed along 1
F = -qË
i.e Fe acts in opposite direction to that of E(r)
As force on the electron
... Force on electron placed at A as well as as at B acts along 3
Also F. decreases as
for A whereas increases as r for B.
