What is the purpose of a pulley?
Will it change only the direction of the force, without any change in the magnitude?
Then, will the spring balance 'B' show the reading of the load (weight)?
Will spring balance 'B' show the reading of the load (weight)?
Will spring balance 'B' exert force on the spring balance 'A'?
Is the force acting on both the spring balances the same?

For the arrangement shown in the figure, the reading of spring balance is

`50 N`

`100 N`

`150 N`

None of the above

Two masses m_(1) and m_(2) are attached to a spring balance S as shown in figure. m_(1) gt m_(2) then the reading of spring balance will be . .

`(m_(1)-m_(2))`

`(m_(1)+m_(2))`

`(2m_(1)m_(2))/(m_(1)+m_(2))`

`(m_(1)m_(2))/(m_(1)+m_(2))`

A body of mass 5 kg is suspended by a spring balance on an inclined plane as shown in figure. The spring balance measure
