i have this question its worth 12 marks so i'm just wondering if i did it properly. the question is "the following diagram shows two charged objects, 1 and 2, and their positions relative to point p"(adsbygoogle = window.adsbygoogle || []).push({});

object 1 ----------------object 2---------------p

q1=+6.00microC q2=-3.00microC

distance between q1 and q2 is 2.00m and distance between q2 and p is 1.00m

"calculate the magnitude and direction of the resultant electric field at point p.

so this is what i did

[E1]=kq1/r (8.99x10^9 N.m2/C2)(6.00x10^-6C)/(2.00m)^2

=13485N/C

[E2]=kq2/r (8.99x10^9 N.m2/C2)(3.00x10^-6C)/1.00m)^2

=26970N/C

than i went [Ep]=[E1+E2]

13485N/C+26970N/C

=40455N/C

so my final answer is 4.05x10^4N/C to the right.

is this correct. thanks
