Is it possible that an object is in the state of accelerated motion due to external force acting on it, but no work is being done by the force? Explain it with an example.

yes in case of vertically projected body it has acceleration but after some time it will come back again to the initial position
we know that displacement = final position-initial position
in this case displacement is zero
so work done =force × displacement
=force× 0
=o (zero)
so work done is zero in case of vertically projected body on earth
