A man of mass 60 kg is standing on a weighing machine (2) of mass 5kg placed on ground. Another identical weighing machine is placed over man’s head. A block of mass 50kg is put on the weighing machine (1) . Calculate the readings of weighing machines (1) and (2) .

Answer

500 N, 1150 N

Explanation

`R_(1)=N_(1)=50xxg=500N`
where `R_(1)` = reading in weighing machine 1

`R_(2)=N_(3)=(50+5+60)g`
`=115xx10=1150N`
where `R_(2)` = reading in weighing machine 2
