Physics Problem NEED HELP!!!!!!?

It takes 4.0 uJ of work to move a 11 nC charge from point A to B. It takes -6.5 uJ of work to move the charge from C to B.

Answer 1

it actually is the answer the units are slightly wrong
11 nC = 11 * 10^-09
and 4.0 uJ = 4.0 *10^-6

W = qV is the point charge work formula

4.0 uJ = 11*10^-9*Va
Va = 4.0*10^-6/11*10^-9volts
Va = 3.6 * 10^2
the other is
-6.5 uJ = 11nC * Vc
Vc = – 6.5*10^-6/11*10^-9 volts
Vc = -5.9*10^2

V = Vc – Va = -5.90*10^2 – 3.6*10^2 = -9.5*10^2

sorry about the unit screw up
