The force constant of a wire is k and that of another wire is When both the wires are stretched through same distance, then the work done.
The force on a particle as the function of displacement x(in x-direction) is given by
The work done corresponding to displacement of particle from to unit is?
A body of mass travels in a straight line with a velocity where is a constant. The work done in displacing the body from to is proportional to:
A body is acted upon by a force which is proportional to the distance covered. If distance covered by denoted by x, then work done by the force will be proportional to:
