Check to see if this is done correct

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"
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

Almost. Note though, that the distance from q1 to p is
'the distance from q1 to q2'+'the distance from q2 to p'.

Also, the q2 is negatively charged. Don't forget that minus sign.

Yes, your calculations appear to be correct. However, it would be helpful to show the direction of each electric field vector in your solution, as well as the direction of the resultant electric field at point p. This can be done using vector notation or by indicating the direction with words (e.g. "to the right"). Additionally, it would be beneficial to include the units for your final answer (N/C). Overall, your solution seems to be correct, but including these details would make it more clear and complete.
