statement A if an object is lifted from the ground to a certain height

1.	statement A if an object is lifted from the ground to a certain height work done by the gravitational force is negative statement B if an object is lifted from the ground to a certain height work done by lifting force is positive
Answer» these statements are correct. This is because :-Statement 1 :-WORK is DONE but in opposite direction. Therefore, work done becomes negative.Statement 2 :-Work is done in direction of displacement PRODUCED. So, work done is positive.
