Question

to study the 3rd law of motion ,following sets of apparatus are available in laboratory

set[1] 1 spring balance,2 weight boxes,inextensible thread, 1 pulley with a clamp, 2 pans of known mass

set[2]2 identical spring balances,1 weight box ,1 frictionless pulley with a clamp, 1 pan of known mass,inextinsible thread,rigid support

set[3] 4 identical spring balances,2 pulley, 2 pan of known mass,inextinsible thread,2 rigid support, 2 clamps

set[4] 2 identical spring balances,2 weight box ,2 frictionless pulley with a clamp, 2 pan of known mass,inextinsible thread,2 rigid support

to perform experiment successfully by using minimum apparatus ,the best choce would be which of the above sets?

Answer 1

To perform the experiment successfully by using minimum apparatus, the best choice would be set (2) in which we use two identical spring balances, one weight box, one frictionless pulley with a clamp, one pan of known mass, one inextensible thread and a rigid support.
