Question

torque in electric displacement

Answer 1

Electric displacement (D), also known as electric flux density, is the charge per unit area that would be displaced across a layer of conductor placed across an electric field.

And Whereas,

Torque is the twisting force that tends to cause rotation. The point where the object rotates is known as the axis of rotation. Mathematically, torque can be written as T = F * r * sin(theta), and it has units of Newton-meters.
