1. The problem statement, all variables and given/known data A dust particle with mass of 0.043g and a charge of 2.0 * 10^(-6)C is in a region of space where the potential is given by V(x) = (2.0V/m^2)x^2 - (3.0V/m^3)x^3. If the particle starts at x = 2.1m, what is the initial acceleration of the charge? Your explanation will be extremely helpful. Thank you for taking the time to look at this question. 2. Relevant equations Vba = (Ub-Ua)/q dU = qVba Vba = Vb - Va V = (1/(4pieo))*(Q/r) 3. The attempt at a solution I don't even know where to begin with this question.
