1. The problem statement, all variables and given/known data Find the electric field produced by a 2.5uC point charge at distance of 0.75m. E = ___ V/m 2. Relevant equations E = kq/r^2 3. The attempt at a solution E = (9x10^9 Nm^2/C^2)(25)/(0.75)^2 = 400 x 10^9 My concern is about the units I am being asked. Since K is using Nm^2/C^2, how do I convert it to V/m IF IT´S CORRECT, of course. Thanks in advance!!
