$V_{AB} = - 2, 8 V$ $V_"AB"=-2,8V$

Explanation:

$Voltage between two points is given by V_{AB} = \frac{W_{AB}}{q}$ $"Voltage between two points is given by " V_"AB"=W_"AB"/q$
$where W_{AB} : work done between A and B ; q:charge$ $"where "W_"AB": "work done between A and B ; q:charge"$

$W_{AB} = 18 - 32 = - 14 J$ $W_"AB"=18-32=-14J$
$q = 5 C$ $q=5C$

$V_{AB} = - \frac{14}{5}$ $V_"AB"=-14/5$

$V_{AB} = - 2, 8 V$ $V_"AB"=-2,8V$
