A neutral spherical copper particle has a radius of 10   nm 1   nm = 10 - 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
Correct answer
0
Step-by-step solution
From V = k q r , q = V · r k = C · V As, q = n e , hence graph of q versus V is a step function.
