Para llevar una carga (1000 newton) una distancia de 50 metros una persona tarda 10 minutos, mientras que otra persona en las mismas condiciones tarda 5 minutos ¿quién hace más trabajo? ¿Quién tiene más potencia?

Explanation:

"To carry a load (1000 newton) a distance of 50 meters a person takes 10 minutes, while another person in the same conditions takes 5 minutes, who does more work? Who has more power?"

Work = force × distance

Both people exert the same force over the same distance, so they do the same amount of work.

Power = work / time

The second person does the same amount of work but in half the time, so they have twice the power of the first person.

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
