Frictions- two block problems

Similarty Condition of two polygon

Limiting Friction and Block on Incline

Find out the range of force in which both the blocks move together.

In above example find maximum F for which two blocks will move together.

Condition for Perpendicularity of two lines.

Friction Between Two Blocks

The limiting friction between two surface does not depend

Which factor is not limiting in normal conditions for photosynthesis

A block of mass 2kg is placed on a trolley of mass 20 kg free to move on a frictionless floor. What are the frictional force, accelerations of the block and trolley if the block is pulled by a force of 3 N ? The coefficient of friction between block and trolley is 0.25. What will be the values of all three if the block is pulled by 8 N force ? At what value of the applied force will the bodies just tend to separate ? [Hint : So long as the force applied does not produce the limiting frictional force the two will move with common acceleration. When the force applied exceeds that limiting value the block will move on the trolley with a different acceleration]
