Answer 1

Answer:

30kg

Explanation:

Distance between Alok and father = 5m

Father's distance from fulcrum  = 2m

Slok's weight  = 20kg

Unknown:

Weight of the father = ?

Solution:

This problem entail the balancing of forces around a fulcrum.     In this problem;

workdone by father =  workdone by Alok            

( mass x distance) father  = (mass x distance) Alok  

distance of Alok from the fulcrum  = 3m  

Input the parameters and solve;          

mass of father x 2  = 20 x 3      

mass of father  = 30kg

The weight of the father is 30kg
