AIPMT 2008 | Electrostatics Question 55 | Physics

Three point charges +q, $$-$$ 2q and + q are placed at points (x = 0, y = a, z = 0), (x = 0, y = 0, z = 0) and (x = $$a$$, y = 0, z = 0) respectively. The magnitude and direction of the electric dipole moment vector of this charge assembly are

$$\sqrt 2 qa$$ along the line joining points (x = 0, y = 0, z = 0) and (x = $$a$$, y = a, z = 0)

q$$a$$ along the line joining points (x = 0, y = 0, z = 0) and (x = $$a$$, y = a, z = 0)

$$\sqrt 2 qa$$ along +x direction

$$\sqrt 2 qa$$ along +y direction.
