[" The work done in extending a spring by "x_(0)" is "],[W_(0)" .Find the work done in further extension "x_(0)" ."]

STATEMENT-1: An elastic spring of force constant k is stretched by a small length x. The work done in extending the spring by a further length x is 2kx^(2) . because STATEMENT-2: The work done in extending an elastic spring by a length x is proportional to x^(2) .

A magnet of moment M is lying in a magnetic field of induction B. W1 is the work done in turning it from 0^(@) to 60^(@) and W_(2) is the work done in turning it from 30^(@) to 90^(@) . Then

Work done by a spring force is

On which the work done by a spring depends ?

The force on a particle is directed along an x axis and given by F= F_(0) (x//x_(0)-1) . Find the work done by the force in moving the particle from x=0 to x= 2x_(0) by (a) plotting F(x) and measuring the work from the graph and (b) integrating F(x) .
