Question

Q-1 write the value of charge and mass of election?
Q-2. How many electron constitue a charge of three
coulumbs.?
​

Answer 1

CHARGE OF ELECTRON=>1.6×10^-19

MASS OF THE ELECTRON=>9.1×10^-31

1 ELECTON HAS 1.6×10^-19 coulombs of charge

1 CHARGE =1/1.6×10^-19 Electrons

= 6×10^18

3 CHARGES=3×6×10^18 ELECTRONS

=18×10^18 ELECTRONS

Answer 2

Q1. the charge of electron is positive

and mass of electron is approximately

9.109×10^-31

Q2..we know that one coloumb of charge have 6 multiplied by 10 power 18 electrons

so, three coloumb of charge have ( 6×3×10) power18 electrons
