A particle is moving in a uniform circular motion of radius \( R \) with angular velocity \( \omega \) in the anti-clockwise direction. Another particle is also moving along the same circular path but in the clockwise direction with the same angular velocity \( \omega \). Suppose, both the particles start at \( t = 0 \) from the same point (R, 0) in opposite directions. The minimum time \( t \) after which the velocities of the two particles become orthogonal to each other is:
The torque of a force \( \mathbf{F} = 4\hat{i} - 2\hat{j} + 3\hat{k} \) about the origin is \( \mathbf{r} \). The force acts on a particle having position vector \( \hat{i} + 2\hat{j} - \hat{k} \). Then the torque \( \mathbf{r} \) is:
