A stone of mass 10 kg is placed on the horizontal floor and it is pulled by a force F acting at angle 45°. What is tension in the string when it breaks off from the ground? (g = 10m/s2).

Given,

Mass of the stone, m = 10kg

Angle at which the force is acting = 45o When vertical component of the applied force is equal to the weight of stone, the stone will lose contact.

i.e., F sin45o = 100 Therefore tension in string is 116 Views

What are the basic characteristics that a quantity must possess so that it may be a vector quantity?

A quantity must possess the direction and must follow the vector axioms. Any quantity that follows the vector axioms are classified as vectors.
