Here, qA = 2
C = 2 x 10-6C
and qB = - 2C = -2 x 10-6C
AB = 16 cm
r = OA = OB = 8cm
E = ?
Electric filed is the on unit positive charge (+1C) at O.
E = k 
EOA = EOB
E = 2EOA
E = 
E = 3.6 x 106 NC-1 along OB

Expert Answer:
The answer had a substitution error.
In place of 10-1, 8×10-2 should be substituted.
