Question

- The mass of the earth is 6.0 x 1024 kg. The potential
energy of a body of mass 50 kg at a distance of
6.3 x 100 m from the centre of the earth is​

Answer 1

Answer:

Potential energy is the product of the mass of the object, its height from the earth and the gravitational force it experiences.

According To The Question:

Mass of the object = 50 kg

Gravitational acceleration (g) = 9.8 m/s² [Acceleration due to gravity is constant for all objects on earth]

Height of the object (h) = 6.3 x 100 m = 630 m

P = m x g x h ---------------- Formula for finding potential energy of an object

P = 50 x 9.8 x 630 [Putting all the values in the formula]

P = 3,08,700 Joules

Therefore, the potential energy of the given object is 3,08,700 Joules.
