In a circular motion ,any body move along the radius

Nurut Kkw 4 years, 3 months ago

Centripetal force is the force required to move a body uniformly in a circle. This force acts along the radius to the centre. => according to Newton first law of body cannot change it direction by itself. Some external force is required for this purpose. And this external forces is called centripetal force.

ANSWER

a block of mass25kg is raised by A50kh man in two different ways as shown IN what is the action froce of700N which mode should the man adopt to lift the block without the floor yielding

Posted by Priyajit Patra 4 years, 3 months ago

2 answers

Tabrez Alam 4 years, 3 months ago

750N and 250N in the respective cases; Method (b) Mass of the block, m= 25kg Mass of the man, M= 50kg Acceleration due to gravity, g= 10m/s² Force applied on the block, F= 25×10=500N Case (a): When the man lifts the block directly In this case, the man applies a force in the upward direction. This increases his apparent weight. Action on the floor by the man =250+500=750N Case (b): When the man lifts the block using a pulley In this case, the man applies a force in the downward direction. This descreases his apparent weight. Action on the floor by the man =500-250=250N If the floor can yield to a normal force of 700N, then the man should adopt the second method to easily lift the block by applying lesser force.
