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*109  N-m2/c2

r= .05 m

ϴ =60 degree

By using equation 1 and 2 and given quantities

Fnet = 2(9*109 *(2 *10-6 )2/(.05)2 cos30

=24.94 N
