Un pesado yunque cuelga de una cuerda sujeta al techo, como se muestra en la imagen. Una cuerda idéntica cuelga de la parte
inferior del yunque. ¿Cuál cuerda se rompe si se tira rápidamente
hacia debajo de la cuerda inferior?​

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
