Q- A fulcrum is created by balancing a ruler on a pencil in the middle. Six one rupee coins are placed at 10 cm to the left of the pivot point.
(a) what is the torque exerted by the stack of the six coins about the pivot point if each coin has a mass of 10 grams?
(b) if the ruler is to be balanced again where you have to place the stack of other four coins?
