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.

Explanation

Given that work done by a body on application of a constant force is directly proportional to the distance travelled by the body.
(W) work done `prop` distance (s)
W=F.s
(where , f= arbitrary constant which takes the value 5 uinits) w= 5s

Now , plot the points O (0,0), A(1,5) and B(2,10) on graph paper and joining them to get a line AB.
(i) From point B(2,10) draw a liine parallel to oy to intersect the x- axis at (2,0) and draw a line parallel to x- xis intersect at C(0,10).
Work done when the distance travelled by the body is
2 units =10
