unit positive charge hi kyun liya

5 years ago by Ritik Jatav

Post your answer here

Hi sir I have a doubt ,we are saying charge is invariant because it is related to mass,and mass is constant in any frame of reference,but when the electron is moving in speed of light,we have the relation E=mc^2,so now the mass varies ,then charge will also start vary?

THE CHARGE Q0 IS SLIGHTLY DISPLACED ALONG LINE JOINING OF TWO CHARGES.WILL IT PERFORM S.H.M. IF YES THEN FIND TIME PERIOD?

7 years ago by NIRAV KAPADIYA

Ans 1 ->

electrostatic force/mass = acceleration for SHM acceleration = -omega sq. . dist. after getting omega time period = 2pie/omega

7 years ago by Shubham Rangi

Sir please look at the qs.6 asked that what to do to get the static force if we have charge within 2 separate medium? Would the answer be that instead of e0 for vaccum we will write the product of the permittivity of those?

how a isolated conductor acquires charge?

8 years ago by tarun agarwal

Ans 1 ->

a conductor which is isolated from surrounding can never acquire charge... it can be charged then isolated from surrounding...

8 years ago by Physics Galaxy

Post your answer here

Is an isolated conductor neutral or charged?

8 years ago by tarun agarwal

Ans 1 ->

it can be charged by any method then it can be isolated from surrounding...

8 years ago by Physics Galaxy

why charge is quantized or which property of the charge makes it to be quantizised?

9 years ago by sanjanasanikommu

Ans 1 ->

q=ne The quantization of physical charge meansit cannot vary continuosusly and cannot take any arbitrary value.but it can change discontinuously to take any one of discrete set of values for eg.a building can have different floors(1st 2nd etc)but it cannot have a value in between like 1.5. similarly electric charge is quantized.the minimum amount by which a physical quantity can change is called 'quantum'. It is found experimentally that the electric charge of any body large or small...is always an integral multiple of a certain minimum amount of charge.i.e the basic charge of an electron

Ans 2 ->

In NCERT part 1 class 12 Preface it is mention Physics never answers Why . You Question is dealt by a Field named ' Meta Physics '

9 years ago by Ashish Sharma

@ashish sharma actually physics can answer why because in NLM almost all questions havw WHY in them

how to find maximum charge that can be given to a spherical conductor

9 years ago by Manik

Ans 1 ->

when charge is given to any spherical conductor more than its max value then dielectric breakdown takes place of the medium in which the spherical conductor is placed and hence the dielectric medium also behaves as a conductor due to which charge of the spherical conductor can leak.[watch the complete vdo lectures of electrostatics to clear this concept ]

Why is a charge invariant?

9 years ago by Yash Selot

Ans 1 ->

Charge invariance refers to the fixed electrostatic potential of a particle regardless of speed. For example an electron has a specific rest charge.

what happens to volume of body when it became positively or negatively charge?

10 years ago by rajat rathi

Ans 1 ->

If we talk about a bubble with volume V.If -ve charge given to it then it will shrink due to force acting on it towards center as electric field tends inside for negative charge.

10 years ago by MOHIT SHARMA

Ans 2 ->

it remains same ...............!

9 years ago by Karthikesh

Ans 3 ->

I think that the volume of the body will not change as the volume of electron is comparatively negligible to that of the whole body so there is no change in the volume of the body.

9 years ago by Yash Selot

Ans 4 ->

yash! we were not talking in macroscopic level. we were just talking in atomic level.therefore we cant neglect electronic mass.

9 years ago by SIDDHARTH PRADHAN

Ans 5 ->

volume remains unchanged but I think mass changes due to loss and gain of charges.

9 years ago by Steve Islary

Ans 6 ->

as electron also have mass therefore when object get positively charge there will be loss in mass and when negatively charge it will gain mass but as the mass magnitude of electrons are 9.1* 10^-31 threfore loss in mass will be negligible

9 years ago by ROSHAN

Ans 7 ->

constant =density=mass/volume.if mass increases(addition of electron) volume increases .if it is positively charged volume decreases.But this is a theoretical hypothesis.practically since mass of electron is too small.it is almost undetected by the ordinary instruments.
