Question

one end of a string 0 5 m long is fixed to a point A and the
other end is fastened to a small object of weight 8 N the object is
pulled aside by a horizontal force F, untill it is 0 3 m from the
vertical through A Find the magnitude of the tension T in the
string and the force F

Hansraj Rai · Accepted Answer

From the fig it immediately gives us,

and

The object is at rest, and so the forces must be in equilibrium There is no resultant force vertically, so

There is no resultant force horizontally, so

one end of a string 0.5 m long is fixed to a point A and the other end is fastened to a small object of weight 8 N. the object is pulled aside by a horizontal force F, untill it is 0.3 m from the vertical through A. Find the magnitude of the tension T in the string and the force F.
