Answer:
No, it can’t.
Charge on a body should be an integral multiple of 1.6 × 10^-19 C
Mathematically
Q = ne
For this body
n = Q/e
= (4.0 × 10^-19 C) / (1.6 × 10^-19)
= 2.5
2.5 is not an integer. Therefore a body can’t have charge of 4.0 × 10^-19 C

Answer:
no it cant
Explanation:
Q = ne
where Q is charge, n is number of electrons and e is charge of electron
*n has to be an integer*
now,
4*10^9 = 1.6* 10^-19 (n)
n = 4*10^9/1.6* 10^-19
n = 2.5* 10^-10
since n is not an integer therefore it isnt possible
