Question

A balloon, initially neutral, is rubbed with fur until it acquires a net charge of -0.60 nC. (a) Assuming that only electrons are transferred, were electrons removed from the balloon or added to it? (b) How many electrons were transferred?

Answer 1

a

Step-by-step explanation:

Answer 2

(a) electrons are added

(b)
`3.75* 10^(9)`

Step-by-step explanation:

Charge acquired by the balloon, q = - 0.6 nC

(a) As the balloon gets negative charge, so that it means the balloon gains electrons. The electrons are negatively charged, so a body have negatively charged means that the electrons are added to the body.

(b) The charge of one electron is given by e.

e =
`-1.6 * 10^(-19)C`

The number of electrons is given by the ratio of total charge to the charge of one electron.

let there are n number of electrons

`n = (-0.6* 10^(-9))/(-1.6 * 10^(-19))`

n =
`3.75* 10^(9)`
