Dear sunny shah,
V(r) = (1/4 π ε)*   (q1/r1+ q2/r2+ q3/r3+ q4/r4) = (1/4 π ε)*   4*(q/r) = (1/ π ε)*   (q/r)

q1=q2=q3=q4=q

r=sqrt(4^2+4^2)   because  the total lenght of the side is 8cm . the cahrge is at diagonal of the square from the center
r=sqrt(32)  cm    chane to meter

r=(1/10)*sqrt(32) m
ε= 8.854187817...×10−12 A·s/(V·m) = 8.854187817...×10−12 F/m
q=+(10/3)*1/10000000 = (10/3)*  10^-6
Π=22/7

now u can use the formula and values given above. do it so u can get practice and solve the otherparts

All the best.
