Answer:

The value is
$v = 9.18 *10^(6) \ m/s$

Step-by-step explanation:

From question we are told that

The potential difference is
$\Delta V = 0.24 kV = 0.24 *10^(3) \ V$

Generally the the non-relativistic speed of these electrons is mathematically represented as

$v = \sqrt{(2 * e * \Delta V)/(m) }$

Here m is the mass of an electron with value
$m = 9.11 *10^(-31 ) \ kg$

e is the charge on an electron with value
$e = 1.60 *10^(-19) \ C$

So

$v = \sqrt{(2 * 1.60 *10^(-19) * 0.24 *10^(3) )/(9.11*10^(-31)) }$

=>
$v = 9.18 *10^(6) \ m/s$
