Question

An electric dipole of moment
$\overrightarrow p = \left( { - \widehat i - 3\widehat j + 2\widehat k} \right) \times {10^{ - 29}} $ C.m is
at the origin (0, 0, 0). The electric field due to this dipole at
$\overrightarrow r = + \widehat i + 3\widehat j + 5\widehat k$ (note that $\overrightarrow r .\overrightarrow p = 0$ ) is parallel to :

$\left( { + \widehat i + 3\widehat j - 2\widehat k} \right)$

$\left( { + \widehat i - 3\widehat j - 2\widehat k} \right)$

$\left( { - \widehat i + 3\widehat j - 2\widehat k} \right)$

$\left( { - \widehat i - 3\widehat j + 2\widehat k} \right)$
