Q. charges are placed each at a distance 'a' from origin. The dipole moment of configuration is:

$2 q a \hat{j}$

$3 q a \hat{j}$

$2 a q [\hat{i} + \hat{j}]$

None

Here $p_{x} = 0$
and $p_{y} = 2 q a$
$∴ ∣ p_{2} ∣ = ∣ p_{3} ∣$
$& ∣ p_{1} ∣ = ∣ p_{4} ∣$
$\Rightarrow p_{n e t} = 2 q a \hat{j}$

Q. charges are placed each at a distance 'a' from origin. The dipole moment of configuration is:

2qaj^​

3qaj^​

2aq[i^+j^​]

None

Here px​=0 and py​=2qa ∴∣p2​∣=∣p3​∣ &∣p​1​∣=∣p​4​∣ ⇒p​net​=2qaj^​

$2 q a \hat{j}$

$3 q a \hat{j}$

$2 a q [\hat{i} + \hat{j}]$

Here $p_{x} = 0$
and $p_{y} = 2 q a$
$∴ ∣ p_{2} ∣ = ∣ p_{3} ∣$
$& ∣ p_{1} ∣ = ∣ p_{4} ∣$
$\Rightarrow p_{n e t} = 2 q a \hat{j}$
