please give me derivation of coulombs law in detail.

Asked by shivamthetrisal 6th April 2014 11:11 PM

plot a graph showing the variation in coulombs force f versus 1/r2 where r is the distance between two chargesof each pair of (1mc , 2mc) (2mc,-3mc)?

Asked by vasturushi 25th December 2017 7:23 PM

why does coloumb`s force act between two charges only  in the line joing their centres?

Asked by my3shyll 10th April 2018 7:38 PM

why don`t we consider signs of chages while substituting in the coloumb`s law?

Find the elctric force between two protons separated at a separation of 1 fermi . the protons in a nucleus remain at a separation of this order.

Asked by haroonrashidgkp 19th April 2018 8:51 PM

At what separation should two equal charges , 1.0 C each, be placed so that the force between them equals  the weight of a 50 kg person

suppose all the electrons of 100g water are lumped together to form a negatively charged particle and all the nuclei are lumped together to form a positiely charged particle. if these two particles are placed 10.0cm away form each other, find the force of attraction between them.

If 2 identical spheres having charge 16 microcoulomb and -8microcoulomb are kept at a distance apart having force F They are touched and again kept at the same distance then what is the force between the two

Asked by tandonyashika 5th June 2018 11:24 AM

State Coulomb’s law and express it in vector form.

Asked by asraneaf5588 22nd June 2018 8:31 PM

The electrostatic force on a metal sphere of a charge 0.4 macrocoulomb due to another identical metal sphere of charge - 0.8 macrocoulomb in air is 0.2 Newton .find the distance between the two sphere and also the force between same to sphere When They brought into contact and placed in there initial position?

Asked by hemanttkumarr 14th July 2018 7:37 PM

derive coulombs law in vector form

Asked by Prashant Malik 16th August 2018 12:56 PM

Coulomb's law for electrostatic force between two point charges and newton's laws for gravitational force between two stationary point masses both have inverse square dependence on distance between charges/masses. Compare strength of ratio for an electron and proton Two protons
