if a body having mass 2kg is at a having of 5 meter from the ground what is the potential energy if g=10 m/s²​

Answer»

Given :

Mass of the body = 2Kg

Height from the ground = 5m

Gravitational field = 10m/s²

To FIND :

The potential energy of the body

Solution :

Potential energy is energy due to position.

  • Potential energy is SCALAR quantity having magnitude.
  • Sl unit of P.E is Joules.

Potential energy of an object is given by

  • P.E = mgh

where,

P.E denotes potential energy.

m denotes mass.

g denotes gravitational field.

h denotes height.

By substituting all the given values in the formula,

➠ P.E = mgh

➠ P.E = (2)(10)(5)

P.E = 100J{.}

thus, potential energy of the object is 100J.
