Answer : O Joules
Explanation :
When we say The work done by the man, We are talking about the work done by man on the trunk.
As we know,
W = F. S
Here,
F = Force exerted by the man on the trunk.
S = Displacement of the trunk in the direction of applied force.
Since, There is no displacement. S becomes 0, then W = F * 0 = 0
Work done becomes 0.
Hence, The 2 m high person who is holding 25 kg trunk does no work standing at the bus terminus.
