Unit 8: Simple A pulley system has a mechanical advantage of 11. If it needs to lift a 3190 N rock, what force will need to applied by the person using the pulley
system?
For full credit, show the formula, the quantities in the formula, and your final answer with proper units.

102564.103 C

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.
