Question

How many electrons from a piece of metal to give it positive charge of of 1.0 × 10^-7 C ? Pls answer fast and don't spam pls.........​

Answer 1

Answer:

removing each electron will give u 1.603*10^-19 C positive charge. So if u want +1*10^-7 C u need to remove +1*10^-7 / 1.603*10^-19 = 6.2383*10^11 electrons.

Answer 2

Correct Question:

How many electrons must be removed from a piece of metal to give it positive charge of 1.0 × 10⁻⁷C ?

Answer:

6.25 × 10¹¹ electrons must be removed from a piece of metal to give it positive charge of 1.0 × 10⁻⁷C.

Explanation:

We need to find n.

We know that,

Q = ± ne

where the value of e = – 1.6 × 10⁻¹⁹ C.

Now by substituting the values here, we get

Q = ± ne

➳ 1 × 10⁻⁷ = n × 1.6 × 10⁻¹⁹

➳ n = (1 × 10⁻⁷)/(1.6 × 10⁻¹⁹)

➳ n = 6.25 × 10¹¹

Hence solved...
