Question

2. Can an object have a charge of 2.8*
10-18 C ? Justify your answer.​

Answer 1

Answer:

charge is quantized .

Means charge follow Q = ne , algebraic expression.

Where Q is the charge on object .

n is the number of electron present on that object.

and e is charge on electron.

Charge on electron , e = 1.6 × 10⁻¹⁹C

charge on object , Q = 2.8 × 10⁻¹⁸C

Now, n = Q/e = 2.8 × 10⁻¹⁸/1.6 × 10⁻¹⁹ = 17.5

Here , we get number of electron present on object = 17.5 . It is fractional . But we know electron is not divisible . So, fractional number of electrons are not possible. hence, an object can't have a charge of 2.8 × 10⁻¹⁸C .
