Question

a book is placed on a table 9 meters above the ground and has a potential energy of 60j. what is the mass of the book ??


it's Isha​

Answer 1

Step-by-step explanation:

The gravitational potential energy is m×g×h, where, m= mass, g= acceleration of gravity, (9.8m/s2) and h= height from the earth surface.  As potential energy is the energy in a body due to its position ,so when the book is moved to table ,its height increases so it gain the potential energy.
