How much mass (approximately) of a body one can hold, when a force of 1N is applied on it ?
A force of 100 N needs to be applied parallel to a smooth inclined plane just to hold a body on it. The angle of inclination of the inclined plane is 30∘. How much horizontal force needs to be applied to do the same?
How much work is done when a force of 1 N moves a body through a distance of 1m in its own direction?
