given
charge of positron, q = +e
= 1.6*10^-19 C
mass of positron, mp = 9.1*10^-31 kg
a) use, F = q*E
m*a = q*E
a = q*E/m
= 1.6*10^-19*309/(9.1*10^-31)
= 5.43*10^13 m/s^2 <<<<<<<<<-------------Answer
b) given initial velocity, u = 0
t = 6.75*10^-9 s
v = ?
now use, v = u + a*t
= 0 + 5.43*10^13*6.75*10^-9
= 3.67*10^5 m/s <<<<<<<<<-------------Answer
