The energy possessed by a body of mass 2 kg when it is placed at a height of 5 m above the ground will be (g = 10 m/s²)

CONCEPT:

Potential Energy (P.E.)

• Potential energy is the energy possessed by a body due to its position or height above the ground.
• The formula for potential energy is:

  P.E. = m × g × h

• Where:
  • m = Mass of the object (in kg)
  • g = Acceleration due to gravity (in m/s²)
  • h = Height of the object above the ground (in meters)

EXPLANATION

• Mass of the body (m) = 2 kg
• Height of the body (h) = 5 m
• Acceleration due to gravity (g) = 10 m/s²
• Using the formula for potential energy:

  P.E. = m × g × h

  = 2 × 10 × 5

  = 100 J

Therefore, the energy possessed by the body is 100 J.
