Rezolvarea :
[tex]ec = \frac{mv}{2} = v {}^{2} = [/tex]
[tex] \frac{2ec}{m} = \frac{2 \times 4.55 \times 10 {}^{ - 19} }{?} [/tex]
[tex] = 10 {}^{6} \frac{m}{w} [/tex]
[tex]f = ev \beta [/tex]
[tex]f = m \times a = a = \frac{f}{m} [/tex]
F= m ×a => a = F / m = evB / m =
= 1 . 6 × 10 ^ - 19 × 10 ^ 6 × 0 . 3
