Which of the following is not an example of zero work?a)The work done ...
W = F.s = F s cos¢
In option a) displacement (s) along circular path is zero. work done = F.s = F.0 = 0.
In option b) both force (F) and displacement applied. work done is not equal to zero (has some work).
In option c) angle between force and displacement is 90'. work done = F.s = F s cos90' = 0.
In option d) displacement travelled by the person is zero. work done = F.s = 0.
In option a) displacement (s) along circular path is zero. work done = F.s = F.0 = 0.
In option b) both force (F) and displacement applied. work done is not equal to zero (has some work).
In option c) angle between force and displacement is 90'. work done = F.s = F s cos90' = 0.
In option d) displacement travelled by the person is zero. work done = F.s = 0.
