Normal Reaction , Tension and Gravitational Force | explained in HINDI

In this Physics video in Hindi for class 11 we explained normal reaction by ground, tension in a string due to gravitational force. These are very important topics in Newton's laws of motion. When an object is placed in ground, the ground exerts normal reaction on the object to cancel the gravitational force. When an object is suspended by a string, the string exerts tension on the object to cancel the gravitational force. This gravitational pull is equal to the product of the mass of the object and the acceleration due to gravity at that position. We also discussed on the situation when a body is placed on an inclined plane. In this situation we resolve the gravitational force (mg) into two perpendicular axes. One of them is cancelled by the normal reaction and the other one becomes responsible for the acceleration of the body. ************************************************** Click to visit the homepage of our channel :    / @edupoint.physics   Arijit Daripa EduPoint, Dam Road, Chandil, Dist- Seraikela-Kharsawan, Jharkhand, India.
