Question

What will be the height with respect to the ground if an object of mass 1
kg has potential energy of 1 joule? Your option is

(A) 0.564 metre
(B) 0.345 metre
(C) 1.303 metre
(D) 0.102 metre​

Answer 1

Answer:

hey mate here is your answer.....

Explanation:

☑️ D) 0.102 meter

_______________________________________________

▶️ Formula of potential energy is P.E = Mgh

➡️ E = mgh ( here m is mass, g is acceleration due to gravity and h is for height)

➡️ E = 1*9.8*h

➡️ E = 9.8 x h

➡️ 1 = 9.8 x h ( here 1 because the potential energy is of 1J)

➡️ h = 1/9.8

➡️ h = 0.102

Hope it helps!

Answer 2

Given :

Mass of the object = 1kg

Potential energy = 1 J

To find :

The height with respect to the ground

Solution :

Potential energy is energy due to position.

• Potential energy is scalar quantity having magnitude.
• Sl unit of P.E is Joules.
• CGS unit of P.E is erg.

Potential energy of an object is given by

P.E = mgh

where,

• P.E denotes potential energy.
• m denotes mass.
• g denotes gravitational field. (9.8 m/s²)
• h denotes height.

Substituting all the given values in the formula,

➠ P.E = mgh

➠ 1 = (1)(9.8)h

➠ 1 = 9.8h

➠ h = 1/9.8

➠ h = 0.102 m

thus, the height with respect to the ground is 0.102m.

Hence, option (d) 0.102 metre is correct.
