from V =(kq/r), q=(V . r/k)=C.V As, q = ne, hence graph of q versus V is a step function. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/biology/aac4dd1cba196558c0f4102c60695672-.jpeg" />

Q. A neutral spherical copper particle has a radius of $10 nm (1 nm = 1 0^{- 9} m)$ . It gets charged by applying the voltage slowly adding one electron at a time. Then, the graph of the total charge on the particle versus the applied voltage would look like

from $V = \frac{k q}{r},$
$q = \frac{V . r}{k} = C . V$
As, $q = n e$ , hence graph of $q$ versus $V$ is a step function.

Q. A neutral spherical copper particle has a radius of 10nm(1nm=10−9m). It gets charged by applying the voltage slowly adding one electron at a time. Then, the graph of the total charge on the particle versus the applied voltage would look like

from V=rkq​, q=kV.r​=C.V As, q=ne, hence graph of q versus V is a step function.
