Question

A sphere of radius 25cm and mass 1 kg is hung by a string of negligible mass and length 4cm the tensn in tha string is

Answer 1

The tension of the string is T=mg. T= 1X9.8 = 9.8 N.

Tension might be described as the pulling force which is transmitted axially by means of chain, cable, string or similar one-dimensional continuous object or by each end of rod, truss member or similar three-dimensional object.

Tension might also be described as the action-reaction pair of forces acting at every end of said elements.
