Kinetic energy of a particlemoving in a straight line is proportional to the time t.The magnitude of the force acting on the particle is a.directly proportional to the speed of the particleb.inversely proportional to √tc.inversely proportional to the speed of the particled.directly proportional to √tPlz explain ur answer.

The option (c) i.e inveresely  proptional to the speed of the partice might be correct.

Let the Kinetic Energy of the particle is = E

Then E = kt (where k is a constant)

At time t=0 , particle Energy =0

Under a variable force its velocity increses from 0 to E in t seconds

Then E= integration of F . ds

ds can be written as V.dt (velocity) thus E = integration of F . v dt

kt= integration of Fv dt

k.dt= Fv.dt

k= Fv

F= k/v (c.) ----------(ans)
