Homework Statement
The electric field on the x-axis due to a point charge fixed at the origin is given by E=(a/x2)i, where a = 6.00 kVm and x is not equal to zero.
a) Find the magnitude and sign of the point charge
b) Find the potential difference between the points on the x-axis at x=1 m and x=2 m.
c) What is the potential energy of a proton at both positions?
Homework Equations
E=kq/^2
Vb-Va=-∫Edl
The Attempt at a Solution
a) I've got the magnitude but I am unsure how to find the charge?
b) using Vb-Va=-∫Edl, but if I am honest, I am not 100% sure how to use the equation
