a)-Q/2

b)-Q/4

c) Q/2

d) Q/4

## Can the frictional electricity produced during landing of a plane be used for constructive purposes?

As we know that in aeroplane during landing the charged produced in it due to the friction with ground are earthed through its wheels; can this charge be stored with the help of a capacitor and used

## Physics Project Help

I have to make a Physics project on the topic-

“to estimate the charge induced on each one of the two identical styro foam(or pith) balls suspended in a vertical plane by making use of coulombs

## Calculating charge on a body with excess of electrons

How would I calculate the charge on a small sphere with an excess of 5.0 x 10 14 electrons?

We know that charge on an electron is (-) 1.6 x 10-19 C

If the sphere has 5.0 x 10

## How atoms are formed? – Neeraj Asks

Neeraj asks: ”We have read that atoms can neither been created nor been destroyed!I want to know from where atoms came in existence,if they can not been created,also atom contain electron and proton which are negatively and positively charged,i want to know from where these charge came?”   Your question will be answered soon Link to this post!
