3impressed by the amazing response ...... any ways heres the soln as promised ...
two semi circuar conducting plates are fixed parallel to each other and are a distance d apart
in between them a dielectric in form of semicircle of same radius and thckness d is places and
its free to rotate about its center ..... find the torque on the diaelectric when its diameter
makes an angle @ with the horizontal ////////
V across plates = V [3]
dielectric constant = k
radius of all things = R ..
enjoy!!!!!!!!

1is d solution ryt? i dount my answer is entirely diffrent..!
3dE/dt = 0 as no energy is lost in the thing ....................... another approach is by work energy theorm but its too cumbersome....
