Electrostatics question

2004 · Q130

NEETPhysicsElectrostaticsMCQ+4 / −1
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
  1. A
    2q.E and minimum
  2. B
    q.E and p.E
  3. C
    zero and minimum
  4. D
    q.E and maximum
View written solutionFree

Correct answer: C

When the dipole is in the direction of field then net force is qE + (–qE) = 0
