Question

Calculate the magnitude of the electric field (in n/c) at 2.1 m from a point charge of 2.7 µc. You should round the answer to an integer, indicate only the number, do not include the unit.

Answer 1

`q=2.7* 10^-6c r=2.1 E=(kq)/(r^2)  =(9*10^9*2.7*10^-6)/(2.1^2) =(9*10^3*2.7)/(2.1^2) =9*10^3*4.28 =38.52*10^3`
