The resultant force on charge Q because of two equal forces because of other two Q charges planed on equilateral triangle will be given as:-
Fnet = 2Fcos(ϴ/2) ---------------(1)
F=kQ1Q2/r2  --------(2)
in this question Q1=Q2 =Q3 =Q
Given
Q=2 *10-6 c
K=9*10 N-m2/c2
r= .05 m
ϴ =60 degree
By using equation 1 and 2 and given quantities
Fnet = 2(9*10*(2 *10-6 )2/(.05)cos30
=24.94 N

Dear student,
Please find the solution to your problem below.
 
The resultant force on charge Q because of two equal forces because of other two Q charges planed on equilateral triangle will be given as:-
Fnet = 2Fcos(ϴ/2) ---------------(1)
F = kQ1Q2/r2  --------(2)
in this question Q1 = Q2 = Q3 = Q
Given
Q = 2 *10-6 C
K = 9*10 N-m2/C2
r = .05 m
ϴ = 60o
By using equation 1 and 2 and given quantities
Fnet = 2(9*10*(2 *10-6 )2/(.05)cos30o
=24.94 N
 
Hope it helps.
Thanks and regards,
