In the figure four particles form a square with edge length
a=2.44\times 10^(-2)m. The charges are
q_(1)=q_(4)=1.77\times 10^(-15)Cand
q_(2)=q_(3)=q. (a) What is
qif the net electrostatic force on particle 1 is zero? (b) Is there any value of
qthat makes the net electrostatic force on each of the four particles zero? a) Number Units b)
