If there are anyone there that does physics or whatnot, then I greatly appreciate your help on a question that I'm stuck on lol.
Question: The electric potential V in a region of space is given as:
V(x) = Ax^2 + Bx
where V is in Volts and x is in metres.
There is a zero electric potential at the point X0 = -0.45 m. Furthermore when a test charge Q0 = -3.60*10^-6 C moves in this field from the point X1 = 1.85 m to the origin, it does 3.50*10^-5 joules of work.
Determine the values of the constants A and B and their correct SI units.
The answer says A is 2.285 and B is 5.0, but I want to know how to get to the answer.
Thanks.
Andy.
