m When a force Facts at a point p at position from the origin O torque of this force about O is defined ast fxF It is a vector quantity having its direction perpendicular to both r and F according to the rule of cross product When a rigid body is rotating about a fixed axis and a force is applied on it at some point then we are concerned with the component of torque of this force about the axis of rotation not with the net torque When there are more than one force then net torque is given by the vector sum of the torque due to individual force Find the torque of a force F i 23 3k about a point O The position vector of point of application of force from O is F 21 3 k m A 7i 5j k 2i 6j 3k B 3i 5j 4k D none C If the axis of rotation of the body is along the y axis Then what is the component of the torque along the axis in the previous question A 7 Unit C I Unit B 5 unit D zero If F be a force acting on a particle having the position vector F and 7 be the torque of this about the origin then A 7 0 and F 0 C 7 0 and F t 0 B 7 70 and F 7 0 D F 0 and F F 0 force
