Answer:
102564.103 C
Step-by-step explanation:
From the question given above, the following data were obtained:
Energy (E) = 4000 J
Potential difference (V) = 0.078 V
Charge (Q) =?
Thus, we can obtain the charge as illustrated below:
E = ½QV
4000 = ½ × Q × 0.078
4000 = Q × 0.039
Divide both side by 4000
Q = 4000 / 0.039
Q = 102564.103 C
Thus, the charge is 102564.103 C.
