Question
An electric dipole if moment p is placed normal to the lines of force of electric intensity E ,then the work done in rotating it through an angle of 180,is? In this question,which initial angle should be taken ? I am facing problem in application type question ,where I am in dilemma to take which as initial angle

Solution
In this question given that dipole is placed normal to the lines of force of electric intensity.
There for the initial angle is 90 degree
work done (W) = PE(cosø1 - cosø2)
ø1=90°
ø2= 180°
put the values and solve for W
