Question

-A 10 kg iron plate contains 2000 I potential energy at a height. find out its heigt​

Answer 1

To find the height at which a 10 kg iron plate contains 2000 J of potential energy, we can use the formula for potential energy:

Potential energy = mgh

where m is the mass of the object, g is the acceleration due to gravity, and h is the height.

Rearranging the formula, we get:

h = Potential energy / (mg)

Substituting the given values, we get:

h = 2000 J / (10 kg * 9.8 m/s^2)

h ≈ 20.4 meters

Therefore, the height at which a 10 kg iron plate contains 2000 J of potential energy is approximately 20.4 meters.

Answer 2

Assuming that the iron plate is lifted to a height against the gravitational force, we can use the formula for potential energy:

Potential Energy = mass x gravity x height

where mass is in kg, gravity is 9.81 m/s^2, and height is in meters.

Rearranging the formula to solve for height, we have:

height = Potential Energy / (mass x gravity)

Plugging in the given values, we have:

height = 2000 J / (10 kg x 9.81 m/s^2)

height = 20.34 meters (rounded to two decimal places)

Therefore, the height of the iron plate is approximately 20.34 meters.
