STATICS ENGINEERING QUESTION.

14. 0/1 points| Previous Answers OSUniPhys1 24.4.WA.044 My Notes Ask Your Teacher The electric potential in a certain region is represented by the graph shown below. What is the electric force vector on an alpha particle that is at x -1.30 cm and moving to the right? Express your answer in vector form. How is the electric field defined in terms of the variation of the potential at any location? How is the force on a charge related to the electric field in which the charge is situated? Did you take into consideration the sign of the charge? N (10v) 10 8 7 x (cm) 0 2 3 456 Additional Materials eBook

Explanation / Answer

electric field E = -dV/dx = -(1-7)/(2-0.5) *10^3 v/m = 4*10^3 v/m

electric field is along +x direction

electric force F = E*q = 4*10^3*2*1.6*10^-19 i

F = 1.28*10^-15 i N <<<--------ANSWER
