Question

if 10 ki power 10 electrons are removed from a neutral body the charge acquired by the body is​

Answer 1

$\large\underline{\bigstar \: \: {\sf Correct \: Question-}}$

If ${\sf 10^{10}}$ Electrons are removed from a neutral body of charge acquired by the body is.

$\large\underline{\bigstar \: \: {\sf Given-}}$

• Number of electrons removed (n) = ${\sf 10^{10}}$

$\large\underline{\bigstar \: \: {\sf To\: Find -}}$

• Charge on body (Q)

$\large\underline{\bigstar \: \: {\sf Formula \: Used -}}$

$\large\implies\underline{\boxed{\sf Q=ne}}$

e = ${\sf 1.6 \times 10^{-19}\: C}$

$\large\underline{\bigstar \: \: {\sf Solution-}}$

$\implies{\sf Q = 10^{10}\times 1.6 \times 10^{-19}}$

$\implies{\bf Q = 1.6 \times 10^{-9}\: C }$

$\large\underline{\bigstar \: \: {\sf Answer}}$

Charge acquired by the body is ${\bf 1.6 \times 10^{-9}\:C}$

$\large\underline{\bigstar \: \: {\sf Extra \: Info.-}}$

• Like charges repel eachother and unlike charges attract eachother.

• Charge is scalar quantity

• The charge on any body will be some integral multiple of e i.e.,

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀Q ± ne

Where , n = 1, 2, 3....

Charge on any body can never be ${\sf \left(\dfrac{1}{3}e\right), \: 1.5e, \: etc.}$

Answer 2

Given ,

Number of electrons (n) = (10)^10

We know that ,

The total charge on the a body is an integral multiples of electrons i.e

$\large \mathtt{ \fbox{Charge \: \: (q) = ne}}$

Where ,

n = integers

Thus ,

q = (10)^10 × 1.6 × (10)^-19

q = 1.6 × (10)^-9 C

Hence , the charge is 1.6 × (10)^-9 C

EXTRA INFORMATION :

➡Charge is a basic property of matter which is responsible for all electric and magnetic interaction

➡It is denoted by " q "

➡There are two types of charges

• Positive
• Negative

➡The SI unit of charge is Coulomb or Amp•sec

➡Charge is a scalar quantity

➡Like charges repel and unlike charges attract each other with a force (F)

➡F = K(q1q2)/(r)²
