part 3 )
V = kq/r
electric potential is scalar quantity so we can add them
V = kq1/r1 + kq2/r2 + kq3/r3
r1 = r3 = 0.2828 m
r2 = 0.2 m
V = k(q1/r1 + q2/r2 + q3/r3)
V = q1 = -2 uC
q2 = 4 uc
q3 = 6 uc
k = 9x 10^9
V = 307298.44 V
V = 307 kV
part 4 )
V = kq1/r1 + kq2/r2 + kq3/r3
V = r1 = r2 = r3 they are from equi distance
V = k/r ( q1 + q2 + q3 )
q1 = +2 nc
q2 = -1nc
q3 = -1 nc
V = k/r(2 -1 -1)
V = 0 V
