An electric dipole has the magnitude of its charge as $q$ and its dipole moment is $p$. It is placed in a uniform electric field $E$. If its dipole moment is along the direction of the field, the force on it and its potential energy are respectively
  • A$2q \cdot E$ and minimum
  • B$q \cdot E$ and $p \cdot E$
  • C
    Zero and minimum
  • D$q \cdot E$ and maximum
