100 as momentum=mass×velocity
Answer:
electrical conduction through a gas in an applied electric field
Explanation:
Answer:
W = 2.74 J
Explanation:
The work done by the charge on the origin to the moving charge is equal to the difference in the potential energy of the charges.
This is the electrostatic equivalent of the work-energy theorem.

where the potential energy is defined as follows

Let's first calculate the distance 'r' for both positions.

Now, we can calculate the potential energies for both positions.

Finally, the total work done on the moving particle can be calculated.

The answer is A. <span>Some work input is used to overcome friction. </span>
