how charged bodies attract each other ?

SAM_27

charged bodies attract each other depending on the charge.

*Unlike charges attract each other n like charges repel due to electrostatic property.

Jyothi

Opposite charges attract each other according to the Coulomb?s law:

For two charges, Q+ ans Q¯ separated by distance of R, Coulombic

attraction energy, (potential energy) is:

.E = (Q+ . Q¯)/(4ðåoR)

.E = Energy of electrostatic attraction, J (has a negative sign)

Q+ , Q¯ = magnitude of charges expressed as + and - values, (C)

R = charge separation distance, (m)

åo = 8.854 x 10-12 C2/(J.m)

ð = 3.14159

Bringing opposite charges together results in attraction and a lowering

of energy producing a negative value

Good but if you want to know the fundamental behind it. No one exactly knows. We know it just by observation

sampa

to answer this questions pay ur attention towards the properties of charges

1. like charges repel & unlike charges attract each other

2. electrostatic induction -

transfer of electrons takes place

~each charged body attract light uncharged body.

~each conducting body posses free electrons.

~bodies may be charged permanently by electrostatic induction too.

Even an electrically neutral body can attrract a charged body as the body becomes deficient in eletrons or exess of electrons when it attracts +vely or -vely charged body respectively.
