When a steady torque is acting on a body, the body

  • Option 1)

    Continues in its state of rest or uniform motion along a straight line

  • Option 4)

    Rotates at a constant speed

As we learnt in 

Torque -

\underset{\tau }{\rightarrow}= \underset{r}{\rightarrow}\times \underset{F}{\rightarrow}   

 

- wherein

This can be calculated by using either  \tau=r_{1}F\; or\; \tau=r\cdot F_{1}

r_{1} = perpendicular distance from origin to the line of force.

F_{1} = component of force perpendicular to line joining force.

 

 The body rotates at a constant speed.
