6. If the work done by a body on application of a constant force is directly proportional to the distance travelled by the body, express this in the form of an equation in two variables and draw the graph of the same by taking the constant force as 5 units. Also read from the graph the work done when the distance travelled by the body is 0 unit
Let work done be y and distance be x.
Given : Constant force = 5 units
Work done by a body on application of a constant force is directly proportional to the distance travelled by the
i.e.
k=Constant force = 5
Then,
For graph,
Put x=0,we have
Put x=1,we have
Put x=2,we have
Points are (0,0) , (0,5) and (2,10)
If distance travelled is 0 units than work done is 0 units.
