6. If the work done by a body on application of a constant force is directly proportionalto the distance travelled by the body, express this in the form of an equation in twovariables and draw the graph of the same by taking the constant force as 5 units. Alsoread from the graph the work done when the distance travelled by the body is(i) 2 units(ii) O unit

1.	6. If the work done by a body on application of a constant force is directly proportionalto the distance travelled by the body, express this in the form of an equation in twovariables and draw the graph of the same by taking the constant force as 5 units. Alsoread from the graph the work done when the distance travelled by the body is(i) 2 units(ii) O unit
Answer» LET X units be the distance traveled by the body and y units be the work done by CONSTANT force.According to problem, y=5x ...(1)Now , putting the value x=0 in (1)y=5×0=0So, the solution is (0,0)Putting the value x=1 in (1)y=5×1=5So, the solution is (1,5)Putting the value x=2 in (1)y=5×2=10So, the solution is (2,10)(i) When x=2 units (distance)Putting the value x in (1)y=5xy=5×2=10.Hence, Work done =10.(II) When x=0 units (distance)Putting the value x in (1)y=5xy=5×0=0.Hence, work done =0.ᴘʟᴇᴀsᴇ ᴍᴀʀᴋ ɪᴛ's ʙʀᴀɪɴʟɪᴇsᴛ
