Question

A mass of 10kg is at a point A and B is horizontal what is the work done on the object by the gravitional force? explain your answer​

Answer 1

Answer:

work done on the object = change in potential energy

here height is 0 .

equation for potential energy = mgh

so h =0 so work done=0  

Explanation:

Answer 2

Answer:

The weighing machine measures this apparent weight and hence the mass indicated by it is less than the actual mass. Our actual mass will be more than 42 kg.
