Question

electron travel 0.1 metre in uniform electric field of 3200 volt /metre. it enters with 4×10 ^7m/s perpendicular to field. find its deviation

Answer 1

In y direcn.

y = 0.5×(eE/m)×t^2

put the value of charge mass and given electric field inensity

and get the reln. in y and t.

 

Calculate t from:

x = v×t

0.10 =
$4 \times {10}^{7} t$


 

and put it in y eqn. and the deviation value .i.e. y.

answer comes 176 mm
