Question

State whether true or false.

If F is force and r is radius, then torque is given by $\overrightarrow{r}\cdot \overrightarrow{F}$.

• A. True
• B. False

Answer 1

The correct option is B False

Torque is the twisting force that tends to cause rotation.

The torque is defined as the cross product of force and position vectors.

Thus, torque $\tau =\overrightarrow{r}\times \overrightarrow{F}$
