Solution

The correct option is B vertically upward
$\to T = \to r \times \to F$
$= (r^(- j)) \times (F^(i))$
$∴$ direction of Torque is vertically upward according to right hand thumb rule.

If the direction of position vector →r is towards south and the direction of force vector →F is towards east, then the direction of torque vector →T is

The correct option is B vertically upward→T=→r×→F=(r^(−j))×(F^(i))∴ direction of Torque is vertically upward according to right hand thumb rule.(negative sign has no significance because it will simply change the direction)
