It takes 2.5 uJ (microjoules) of work to move a 10nC charge from point A to B. It takes -6.0 uJ of work to move the charge from C to B.
What is the potential difference; Vc-Va (in volts)
Thank you in advance!

Ub - Ua = 2.5uJ
Uc - Ub = -6 uJ
Add the 2 equations
Uc - Ua = -6 +2.5 uJ = -3.5 uJ
Vc - Va = (Uc-Ua)/q = -3.5 x 10^-6 / 10^-8 = --350 Volts
Uc - Ub = -6 uJ
Add the 2 equations
Uc - Ua = -6 +2.5 uJ = -3.5 uJ
Vc - Va = (Uc-Ua)/q = -3.5 x 10^-6 / 10^-8 = --350 Volts
