Here, qA = 2Here, qA = 2C = 2 x 10-6C
and qB = - 2C = -2 x 10-6C
AB, Question no 80570, Physics-6C

and qB = - 2Here, qA = 2C = 2 x 10-6C
and qB = - 2C = -2 x 10-6C
AB, Question no 80570, Physics-6C

AB = 16 cm

r = OA = OB = 8cm

E = ?

Electric filed is the on unit positive charge (+1C) at O.

E = k Here, qA = 2C = 2 x 10-6C
and qB = - 2C = -2 x 10-6C
AB, Question no 80570, Physics

EOA = EOB

E = 2EOA

E = Here, qA = 2C = 2 x 10-6C
and qB = - 2C = -2 x 10-6C
AB, Question no 80570, Physics

E = 3.6 x 106 NC-1 along OB

The answer had a substitution error.
 
In place of 10-1, 8×10-2 should be substituted.
 
Hence, the answer comes out to be 5.6 × 106 NC-1 along OB.
