# 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 2) Gets linear acceleration Option 3) Gets angular acceleration 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.

Option 1)

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

incorrect

Option 2)

Gets linear acceleration

incorrect

Option 3)

Gets angular acceleration

incorrect

Option 4)

Rotates at a constant speed

correct
