Question 8 of 10 > A particular organic molecule forms an electric dipole by possessing an effective charge separation of 0.173 nm for a pair of +1.60 x 10 C charges. What is the magnitude of the molecule's electric dipole moment? electric dipole moment: Find the magnitude of the torque that acts on the molecule when it is immersed in a uniform electric field of 1.67 x 10 N/C with its electric dipole vector at an angle of 58.1" from the direction of the field. torque: angles between the electric field and the electric dipole vector. What is the greatest magnitude of torque Consider all possible angles between the electric field and the electric dipole vecto that the electric field can exert on this molecule? N.m greatest torque: < Question 9 of 10 > A finite line of charge with linear charge density 20 x 10 C/m and length L = 0.852 m is located

Answer 1

Here, C.m means Coulomb. meter

if I in seperation vector between two charger Iq , then the dipole moment, 3 = ad ; [d is meesured - from the ve' charge to ponitive chargé So, magnitude of dipole moment, d=0.173 nm D = ud = 0.173x109 m = 1.6 X0.173 x 10 cm | Q = 1.6 x 10-19 C - D= 0.2768 x 10-28 cm 68 x 10 cm magnitude of dipole moment. -28 D = 2.768

B if dip the dipole moment and Elip the I applied electric field, then torque acting an the dißole, a =D X E magnitude of terque, a= DE sino ; [o ip the so between D & E if o = 58.10 and E= 1.67X105 Me, then the magnitude of torque, = 2.768 X 1.67 * (sin 58.1") x 1024 N.m > Ĉ= 3.92 44 x 10-24 Mom O a=DE Sino 1, here, D&E are constartp. meqnitude of magnitude of electric field dipole moment So l ip maximum when sind in maximum & we know, sino can have maximum value of when o= 90 So greatest magnitude of torque ip, Kran - DE ; [as singu =] I = 2.768 x 1.67x 10-24 N.m = 4.622564 10-24 N.m max = 4.622564 10-24 N.m

Please give a thumbs up if you are satisfied with the solution.
