1.	An object of mass 5 kg falls from a height of 5 m above the ground. The loss of potential energy of the mass is:A. 250 J B. 25 J C. 2.5 kJ D. 50 J
Answer» Given, Mass = 5 kg Height = 5 m Let g = 10 ms^-2 Potential energy stored in a body of mass m and height ‘h’ will be given by = m × g × h = 5 kg×10 ms^-2×5 m = 250 J When the mass falls completely, same potential energy is lost = 250 J

An object of mass 5 kg falls from a height of 5 m above the ground. The loss of potential energy of the mass is:A. 250 J B. 25 J C. 2.5 kJ D. 50 J

Answer»

Given,

Mass = 5 kg

Height = 5 m

Let g = 10 ms^-2

Potential energy stored in a body of mass m and height ‘h’ will be given by = m × g × h

= 5 kg×10 ms^-2×5 m

= 250 J

When the mass falls completely, same potential energy is lost = 250 J
