A man of mass `60kg` is standing on a weighing machine kept in a box of mass `30kg` as shown in the diagram If the man man ages to keep the box stationary, find the read ing of the weighing machine
.

Text Solution

Verified by Experts

we know that Normal reaction =scale reading
For man `T =Mg -R`
For box: `T =mg +R`
`Mg -R =mg + R, 2R =(M -m)g`
`R =((60 -30)xx10)/(2) =150N`
