Question

A 10kg iron plate contains 200j potential energy at a height . Find out it's height.

Answer 1

Answer:

73.46 m

Explanation:

Given,

Potential Energy, PE = 200 J

mass, m = 10 kg

acceleration due to gravity, g = 9.8 m/sec. sq.

$potential \: energy \: = mgh$

$200 = 10 \times 9.8 \times h$

$h \: = \frac{200}{10 \times 9.8}$

$h = 73.46 \: m$

Answer 2

Answer:

2m

Explanation: Given,

Potential Energy, PE = 200 J

Gravity=10

mass, m = 10 kg

now,

PE=mgh

200=10*10*h

200/100=h

2=h
