Yes due to mass they will but due to higher magnitude of electrostatic force they will repel

Yes possible but Only when one have high magnitude change by induced force Let A and B are two changes and A have high magnitude so it produce an opposite change on B and some cancel by own chance on B but not completely cancel so they attached by A

ANSWER

With a certain unknown resistance X in the left gap and a resistance of 8 ohm in the right gap, null point is obtained on the metre bridge wire. On putting another 8 ohm in parallel with 8 ohm resistance in the right gap, the null point is found to be shift by 15cm. Find the value of X from these observations.

Sia ? 6 years, 3 months ago

The potential difference induced across the ends of a coil of wire is equal to the time rate of change of the magnetic flux through that coil of wire. This potential difference is known as an induced "electromotive force" or as an induced emf.

Rishabh Rathi 6 years, 3 months ago

Its simple oxygen is more electonegative and Hydrogen is less electronegative that mean ki joh electron hydrogen ka hai vo oxygen apni taraf kr lega jiske karan oxgen par partial negative and hydrogen par partial positive charge ayega. Dipole ka matlab hota hai ki partial positve se partial negative ki taraf vector draw kro agar resultant zero hai toh molecule non polar hoga aur agar resultant zero nhi hai toh molecule polar hoga.

Rishabh Rathi 6 years, 3 months ago

Actually real resoning of it being polar is that O is more electonegative than H thus it shifts H electron towards it, now it has a bent shape so the vectors of electrons charge add up making a net dipole in the molecule and a molecule which has net dipole or partial charges on atom(since dipole is between partially charged) is called polar.

If you were looking for a simle defination then: Charging is said to be done when a neutral body aquires a charge by any method of charge i.e. conduction, induction or simple rubbing. Discharging is said to be done when a charged body is made neutral either by transferring the charge or by earthing* it. *Technically both are same but all the things are not simple we just love complicating things!!

What is EMF? and Internal resistance

Posted by Sachin Kumar 6 years, 3 months ago

CBSE > Class 12 > Physics

1 answers

Sia ? 6 years, 3 months ago

Electromotive force, abbreviated emf, is the electrical action produced by a non-electrical source. A device that converts other forms of energy into electrical energy, such as a battery or generator, provides an emf as its output.
Internal resistance usually means the electrical resistance inside batteries and power supplies that can limit the potential difference that can be supplied to an external load.
