CBSE Class 11-science Answered

sir i wanted the graphs for the following questions- 1. a ball is thrown vertically upward.plot the graph for velocity and time for the period in which ball remains in air. 2.graph for how acceleration due to gravity varies with distance from the center of earth,outwards.plz reply as soon as possible!!

Expert Answer
1) The ball is thrown vertically. Then, it falls down after reaching maximum height. Througout the motion, the acceleration is same, that is acceleration due to gravity. Thus, the velocity-time graph will be a straight line inclined to time axis.
 
 
 
2) The acceleration due to gravity varies with depth as:
g' = g [1 - (d/R)]
 
Thus, g varies directly with depth d.
 
Now, this variation is till the surface of earth, that is, inside the earth.
Outside the eart, g varies as
 
g' = GR2/(R+h)2
 
Thus, variation of g from centre of earth outwards is
