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:

The force constant of a wire is k and that of another wire is $2k$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 $F=10+0.5x$

The work done corresponding to displacement of particle from $x=0$ to $x=2$ unit is?

A body of mass travels in a straight line with a velocity $v=kx^{3/2}$ where $k$ is a constant. The work done in displacing the body from $x=0$ to $x$ is proportional to:

The displacement x of a particle moving in one dimension under the action of a constant force is related to the time t by the equation $t = \sqrt { x} +3$ where x is in meters and t is in seconds . the work done by the force in the first $6$ second is
