An electric current that continually reverses direction over time is known as an ??

In alternating current, the electrons don't move steadily forward. Instead, they just move back and forth. When the electrons in alternating current switch direction, the direction of current and the voltage of the circuit reverses itself.

Explanation:

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
