Question

What is the potential energy of a 0.15 kg apple hung on a 4-m high tree with respect to the ground?

Answer 1

$▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ { \huge \mathfrak{Answer}}▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪$

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 :

• $0.15 \times 9.8 \times 4$

• $5.88 \: \: joules$
