If a charge on the body is ( 1 nC ), then how many electrons are present on the body?
Options
- A( 1.6 10¹⁹ )
- B( 6.25 10⁹ )
- C( 6.25 10²⁷ )
- D( 6.25 10²⁸ )
Correct answer
B. ( 6.25 10⁹ )
Step-by-step solution
We know; q=n e n= q e where q is charge; n is number of electrons; e is electronic charge Given, q=1 nC =1 10⁻⁹ C If a charge on body is 1 nC , then 6.25 10⁹
