Question

A box of weight 100 N is lifted to a height of 10 m above ground. How much potential energy will be stored in the box?
9800 J
1000 J
2000 J
none of the above
.
.​

Answer 1

Answer:

option a 9800 J

Step-by-step explanation:

PE =mgh

m=100

g=9.8

h=10

multiplying.

we get 9800 J

Answer 2

Step-by-step explanation:

Given :-

• Wieght = 100 N

• Height = 10 m

_____________________________

✧ Solution :-

1) We know that:-

• Wieght = Mass × Acceleration

: → 100 = mass × 10

: → 100/10 = mass

: → mass = -100/10-

: → mass = 10 kg

2) We know that:-

• Potential energy = mass × accelerate

: → Potential energy = 10 × 10 × 10

:→ Potential energy → 1000 J

______________________________

Potential Energy stored in the box is

1000 J
