a) force on q1 by q2,
F12 = k*q1*q2/a^2
= k*q1*q/a^2
force on q1 by q3,
F13 = k*q1*q3/a^2
= k*q1*q/a^2
here, F12 and F13 are perpendicualr to each other.
the resultant of F12 and F13,
F123 = sqrt(2)k*q1*q/a^2
force on q1 by q4,
F14 = k*q1*q4/(2*a^2)
net force acting on q1 = 0
so,
F14 = F123
k*q1*q4/(2*a^2) = sqrt(2)k*q1*q/a^2
q4/2 = sqrt(2)*q
==> q = q4/(2*sqrt(2))
= 2.26*10^-15/(2*sqrt(2))
= 7.99*10^-16 C
b) yes.
