Question

Work done by normal force during horizontal motion of
a block of mass mon smooth horizontal surface after
moving distance xis

Answer 1

Hope it will be helpful

Answer 2

Answer:

given =  horizontal motion

             block with mass .

to find = work done

solution =  

            according to question , the horizontal motion of block with mass is perpendicular to the distance covered by body.  

so we can conclude that the work done by gravity will be zero.
