is irt possible that 4×10^-19cb charge is present on any body ?

Dear student

 

As we know

 

Q = ne

 

4* 10^-19 = n * 1.6 * 10^-19

 

n = 4/1.6

 

As this is not an integer. Hence this cam not be possible

 

Hope it helps

Dear student 

No, as the minimum possible is 1.6 x 10^-19, which is the charge of an electron. a body cant have charge without the integral multiples of the charge of elec. As, n is in fraction which is not possible. Hence, a body can''t have a charge of 0.8X10^(-19).

Good Luck
