<h2>QUESTION:- It is easier to lift the same load by using three pulley system than by using two-pulley system.</h2><h2>ANSWER:- IN CASE OF IDEAL PULLEY SYSTEM</h2><h2>REASON:- </h2>
Logic behind is lies behind the mechanical advantage of the provided bt the Pulley system.
as if we calculate the mechanical advantage of the 2 Pulley system we will have the value 2
And if we will calculate the mechanical advantage of the 3 pulley system then we will get the value of 3
so due to extra mechanical advantage we feel it easy to move with 3 pulley system then 2 Pulley system
