Force and torque experienced by an electric dipole in a uniform electric field |
|
Answer» HEYA..... _____________________________________________________________ QUESTION:- force &torque experienced by an electric dipole in a uniform electric field? ANSWER: Consider an electric dipole placed in a uniform electric field of strength E such that it's dipole moment p makes an angle theata with the direction of E Let 2l be the length of the dipole With +Q and -q charges The force on the charges is F+−→ = +qE→ F−−→ = −qE→ The components of force perpendicular to the dipole are: F⊥+ = +qE sinθ F⊥− = −qE sinθ Since the force magnitudes are equal and are separated by a distance d, the torque on the dipole is GIVEN by: Torque (τ) = Force × distance seperating forces τ = d qE sin θ Since dipole moment is given by p = qd And the direction of the dipole moment is from the positive to the negative charge; it can seen from the above equation that the torque is the cross product of the dipole moment and electric field. Notice that the torque is in the clockwise direction (hence negative) in the above figure if the direction of Electric field is positive. Thus, τ = −pE sin θ Or, τ→ = p→ × E→ |τ→| = |p→ × E→| = pE sin θ _____________________________________________________________ Hope it helps ============= |

Distinguish between Resistivity and resistance.GOOD LUCK GUYZZ |
| Answer» RESISTIVITY is the property of the conductor due to which it offers resistance to the flow of current through it . It is measured by the resistance OFFERED by 1M length of WIRE of that material of area of cross section 1 m2. Resistivity of the material depends only on its material and TEMPERATURE. | |

Calculate resistance when one terminal is zero |
|
Answer» A: ELECTRONS are negatively charged, and so are attracted to the positive END of a battery and repelled by the NEGATIVE end. So when the battery is hooked up to SOMETHING that lets the electrons flow through it, they flow from negative to positive. |

Mutual inductance between two magnetically coupled coils depends on |
|
Answer» The mutual inductance is a depends upon • seperation • number of turns The phenomena of inducing current emf in an inductor as a result of GROWTH or DECAY of current in NEARLY inductor is called as mutual induction. If two inductors are coupled inductively then the flux linked in an inductor depends DIRECTLY on the instant current in the the inductor. ¢ is directly proportional to I ¢ = M I where M is called COEFFICIENT of mutual inductance. The value of mutual inductance depend on the linkage of flux which is depending on the separation orientation of the two inductors. The coefficient of mutual induction is numerically equal to the flux linked in the inductor caused by the unit current flowing in the nearby inductor. |
