Question

21. A molecule of a substance has permanent
dipole moment of 10-29 Cm. A mole of this
substance is polarised by applying a strong
electrostatic field of 10% Vm-'. Find total dipole
monient of the substance​

Answer 1

Answer:

the answer is 39 cm it is the answer

Answer 2

Answer:

Dipole moment of each molecules =10

−30

cm.

As 1 mole of the substance contains 6×10

23

molecules

Total dipole moment of all the molecules

$p=6×1023×10−30Cm=6×10−7Cm</p><p>Initial \: potential energy \:  Ui=−pEcosθ=−6×10−7×107cos0o=−6J \: </p><p>Final \: potential energy  \: Uf=−6×10−6×106×cos60o=−3J</p><p></p><p>$

Work done =− (Change in potential energy)

$=−[(−3)−(−6)]=−3J</p><p></p><p>$
