10) which options below are true? [enter your answer as a string of the letter options you believe are correct. for instance, if you think options a, d, and e are correct, then enter "ade"] a) the dipole is never in equilibrium since it will always twist around. b) a dipole whose moment vector is not aligned with a uniform electric field will twist around toward being aligned. c) no net force acts on the electric dipole. d) there are no electric forces exerted on each pole of the dipole. e) none of the above

BC

Explanation:

A)  In a uniform field , dipole can remain in rotational equilibrium as well as linear equilibrium . So statement is wrong.

A dipole whose moment vector is not aligned with a uniform electric field will twist around toward being aligned. Moment vector is aligned along the axis of the dipole. In this position torque acting on the dipole is zero so it is in rotational equilibrium.

On the dipole only torque acts and no net force acts in case of uniform electric  field. In case of non uniform magnetic field, both torque  and force exists. each pole experiences  electric force of equal magnitude.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
