2.5

1.5

0.4

Answer :

D

Answer 2

Answer:
0.4 m

Work or weight here=force * displacement

Explanation:

which implies=>100=20*2
and if height comes as W/H=F*D....It doesn't make sense as H=2.5 but Hypotenuse or displacement is only 2...can't be bigger than Hypotenuse so that's incorrect, so we can do...
...W*H=F*D
=>H=40/100=0.4
Therefore, 0.4 m is our answer for this question...
