Question

An object has an excess charge of −2.4 × 10−17 C. How many excess electrons does it have?

Answer 1

Given

The object has charge,

`-2.4*10^{-17\text{ }}C`

To find

The number of excess electron

Step-by-step explanation

The charge of a electron is

`1.6*10^(-19)C`

Thus nuumber of electrons

`2.4*10^(-17)(1)/(1.6*10^(-19))=150`

Conclusion

The number of electrons are 150
