1.

A dipole of moment vecp is placed in a uniform electric field vecE. The force on the dipole is vecF and the torque is vec(tau)

Answer»

(i), (ii) and (iii) are correct
(i) and (ii) are correct and (ii) is WRONG
only (i) is correct
(i) and (ii) are correct and (iii) is wrong

SOLUTION :Ina uniform ELECTRICFIELD`vecE`, dipoleexperiences a torque `vec TAU`givenby `vec tau= vecp xx vecE`but expreiences no forces. The potenial energyof thedipolein a uniform electricfield ` vecE`is `U = - vecp .vecE` .
