So in this problem, we know that the potential difference off the accelerator is ah uh, 25 key votes. So basically, the maximum value the maxim energy that we come to him for the whole town is ah e equal 25 kilovolts times one year. Alright. What? He means one. Uh Ah. So this is the electric charge. So this gives you 25 K like electoral votes. All right. And the to figure out the frequency of the photo, we can simply utilized f times half equity. So we come to that. The frequency is 6.3 times 10 to the 18th hurts. All right?
