Answer to Question #185967 in Electricity and Magnetism for Tobias Amukwiita

Question

1.0 An electron is shot at 106 m/s between two parallel charged plates, as shown in [5]

figure 1, below. If the field intensity E between the plates is 1KN/C, where will the

electron strike the upper plate? Assume Vacuum conditions.

Take e = 1.6 x 10-19c, m = 9.1 x 10-31kg,

106 m/s

Answer 1

$A=E_k,$

$eEd=\frac{mv^2}{2},$

$d=\sqrt{\frac{mv^2}{2eE}}=53~mm.$
