The potential difference between a storm cloud and the ground is 100 million v. if a charge of 1.2 c flashes in a bolt from cloud to earth, what is the change of potential energy of the charge? express your answer to two significant figures and include the appropriate units.

According to the question,

                                                = 100×10⁶ V

                                                = 10⁸ V

The change in Potential energy:

→

By substituting the values, we get

Thus the above response is right.

Change in potential energy,

Explanation:

Given that,

The potential difference between a storm cloud and the ground is 100 million V,

If a charge of 1.2 C flashes in a bolt from cloud to Earth, q = 1.2 C

We need to find the change of potential energy of the charge. The relation between the potential difference and the potential energy of the charge is given by :

U is the potential energy of the charge

So, the change of potential energy of the charge is . Hence, this is the required solution.
