As we know,

\boxed{ \boxed{potential \:  \: energy = mgh}}

where,

  • m = mass of the object = 0.15 kg

  • g = acceleration due to gravity = 9.8 m/s²

  • h = height attained by the object = 4 m

let's find the potential energy of that Apple :

  • 0.15 \times 9.8 \times 4

  • 5.88 \:  \: joules
