Question

calculate the work done by a passenger standing on a platform holding a suitcase of weight 10 kgwt

Answer 1

here
the passenger is standing on a platform so it's displacement will be zero
since we know that ,
work done=force x displacement
= force x 0
=0
hence the work done is zero.
hope it is the required answer...

Answer 2

Your answer is :-


the work done is zero


because force of suitcase acting downward and passenger standing on platform so , there is no displacement

So, from formula of work done

W = fd

°•° d is zero

•°• W = 0
