Question

n which situation is the maximum possible work done?
a.when angle between force and displacement is 0
b.when angle between force and displacement is 180
c.when angle between force and displacement is 45
d.when angle between force and displacement is 90

Answer 1

\(W=F*d*cos\theta\)
where F=force ,d=distance and \(\theta\) is the angle between F and d
so the W would be maximum when \(cos\theta\)=1
of \(\theta\)=0
