How will the potential energy of a body, raised above the ground to a height of 2m, change with an increase in height by another 3m?
h1 = 2 m.
h2 = h1 + 3 m.
En2 / En1 -?
Potential energy is determined by the formula: En = m * g * h.
En1 = m * g * h1.
En1 = 2 * m * g.
En2 = m * g * h2 = m * g * (2 + 3) = 5 * m * g.
En2 / En1 = 5 * m * g / 2 * m * g = 5/2 = 2, 5.
Answer: with an increase in height by 3 meters, the potential energy increases 2.5 times En2 / En1 = 2, 5.
