What is the change in electric potential energy when the dipole moment of a molecule changes its orientation with respect to e⃗
AleksandrR [38]

Electric potential energy of a dipole is given as

U = - P.E

U = - PE cos\theta

so change in the potential energy is given by

U_f - U_i = (-PEcos\theta_2)- (-PEcos\theta_1)

\Delta U = PE (cos\theta_1 - cos\theta_2)

here initially it was parallel to electric field while finally it is perpendicular to the electric field

so we have

\Delta U = PE(cos 0 - cos 90)

\Delta U = PE

so above is the change in potential energy of dipole

kotykmax [81]

Answer:

D_{B}=1173.98m\\D_{C}=675.29m

Explanation:

If we express all of the cordinates in their rectangular form we get:

A = (1404.77 , 655.06) m

B = A + ( -D_{B} *sin(41) , -D_{B} * cos(41) )

C = A + B + ( -D_{C} *cos(20) , D_{C} * sin(20) )

Since we need C to be (0,0) we stablish that:

C = (0,0) = A + B + ( -D_{C} *cos(20) , D_{C} * sin(20) )

That way we make an equation system from both X and Y coordinates:

A_{x} + B_{x} + C_{x} = 0

A_{y} + B_{y} + C_{y} = 0

Replacing values:

1404.77 - D_{B}*sin(41) - D_{C}*cos(20) = 0

655.06 - D_{B}*cos(41) + D_{C}*sin(20) = 0

With this system we can solve for both Db and Dc and get the answers to the question:

D_{B}=1173.98m

D_{C}=675.29m
