HEY!!
_____________________________
⚫Q = 10C
⚫V = 10 MV = 10×106 V
⚫Energy of the charge particle is given by
⚫E = Q V
⚫10×10×106
⚫⚫108 J
____________________________
▶️Current = 5 A
▶️Current = Charge/ Time
▶️Charge = Current x Time
▶️▶️5 C
▶️1.6 x 10-19C is carried by one electron
▶️▶️5C is carried by 3.125 x 1019 electrons.
