Answer 1

QUESTION:- It is easier to lift the same load by using three pulley system than by using two-pulley system.

ANSWER:- IN CASE OF IDEAL PULLEY SYSTEM

REASON:-

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
