1.

A cylinder is sandwiched between two planks. Two constant horizontal forces F and 2F are applied on the planks as shown Masses of planks and cylinder are indicated in the figure Radius of the cylinder is as shown. Then

Answer»

then the ACCELERATION of the centre of mass of cylinder is `(F)/(35M)`
then the acceleration of the centre of mass of cylinder is `(F)/(26M)`
then the acceleration of TOP of plank is `(17F)/(56M)`
then the acceleration of top of plank is `(2IF)/(26M)`
