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:
The axis is tilted and points to the North Star no matter where Earth is in its orbit. Because of this, the distribution of the Sun's rays changes. ... It also means that the angle at which sunlight strikes different parts of Earth's surface changes through the year.

Explanation:
Given
mass of karen 
Distance covered by Karen =69.6 m
acceleration due to gravity=9.8
inclination
vertically karen move

h=39.72 m
Work done by escalator on karen is equal to change in potential energy of karen
