a pulling force making an angle with the horizontal is applied on a block of weight w placed on a horizontal table. if the angle of friction is , the magnitude of the force required to move the body is the answer C.
Force is an important concept as it influences motion. It can be defined as an interaction that changes the motion of an object if unopposed. But the simple definition of the force is that it is the push or pull experienced by any object. Force is a vector quantity, thus it has both magnitude and direction. Therefore, one has to specify both the direction and the magnitude to describe the force acting on an object.
