Question

The potential difference between a storm cloud and the ground is 1.14 × 108 V. If a bolt carrying 5 C falls from a cloud to Earth, what is the magnitude of the change of potential energy of the charge? 1. 272000000.0 2. 920000000.0 3. 508000000.0 4. 705000000.0 5. 287000000.0 6. 520000000.0 7. 744000000.0 8. 570000000.0 9. 1355000000.0 10. 426000000.0 Answer in units of J.

Answer 1

8).
`U = 5.7 * 10^8 J`

Step-by-step explanation:

Potential energy of charge while it passes two points of given potential difference is

`U = q\Delta V`

so here we know that

q = 5 C

also we know that potential difference of two points are

`\Delta V = 1.14 * 10^8 Volts`

so we have

`U = (5C)(1.14 * 10^8 Volts)`

`U = 5.7 * 10^8 J`
