The answer is True :) have a good day
Electric potential energy of a dipole is given as


so change in the potential energy is given by


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


so above is the change in potential energy of dipole
Answer:
1. Formula = distance/time
D= 112.0 meters, time =4 secs
Speed = d/t =112.0/4
= 28m/s
2.Formula = distance/time
D= 1/4 x 16093.44 m
= 402.35m
Time = 15secs
Speed= d/t
= 402.35/15
=26m/s
