A particle is dropped from a finite height `H` above the ground level under gravity . Due to air resistance acceleration of particle becomes `a=g-kv` in the direction of velocity. Where `k=` positive constant `&v=` speed of particle. Then which of the following graph`(s)` is `//` are possible `(t_(0)=` time when particle touches the ground `):`
