Q30 of 35 Page 55

Distance travelled by the body is directly proportional to time. Is there any external force acting on it?

We know that,

We know that,



Or,


Or, where k = Constant ..1


We also know that,



And,


And,


So,


(From 1)



Now, since a = 0, so force = 0


Hence net external force acting on the particle is zero.
