The charge on one gram of electrons is:
- A
1.7588x10-11
- B
1.7588x1011
- C
1.602x10-19
- D
1.7588x108
We know 1 electron has a mass of 9.1x10²⁸g
So 1g of electrons have how many number of electrons in it ?
No of e= 1g x 1 /9.1x10²⁸g
= 1.098x10²⁷ electrons
Charge on an electron is 1.6x10-¹⁹ C
So charge on 1.098x10²⁷ electrons (weighing one gram) is?
1.098x10²⁷ X 1.6x10-¹⁹ =1.756x10⁸C
As per calculation, this option is incorrect.
We know 1 electron has a mass of 9.1x10²⁸g
So 1g of electrons have how many number of electrons in it ?
No of e= 1g x 1 /9.1x10²⁸g
= 1.098x10²⁷ electrons
Charge on an electron is 1.6x10-¹⁹ C
So charge on 1.098x10²⁷ electrons (weighing one gram) is?
1.098x10²⁷ X 1.6x10-¹⁹ =1.756x10⁸C
As per calculation, this option is incorrect.
