Explanation / Answer

Given

length of the rectangle is l = 0.17 m , bredth b = 0.0585 m

charges q1 = -4.63*10^-6 C, ,q2 = 2.12*10^-6 C,q3 = 3.13*10^-6 C

a) electric potential at point A is  

V = kq/r

V_A = k(q1/l+q2/b)

V_A = 9*10^9((-4.63*10^-6 /0.17)+(2.12*10^-6 /0.0585)) V

V_A = 81036.1991 V

b)

electric potential at point B is  

V_B = k(q1/B+q2/L)

V_B = 9*10^9((-4.63*10^-6 /0.0585)+(2.12*10^-6 /0.17)) V

V_B = -600072.39819 V

C) WORK required to move charge q3 from B to A along diagonal is  

from the definition of potential V = W/q

V_A = W/q3

W = V_A*q3

W = 81036.1991*3.13*10^-6 J

W = 0.253643303183 J
