Torque About A Point

A force of - F hat k on O , the origin of the coordinate system. The torque about the point (1, -1) is. .

A force of -4Fhat(K) acts O, the origin of the coordinate system. The torque about the point (1,-1) is

A force of -Fhatk actgs on O, the origin of the coodinate system. The torque about the point (1,-1) is

Assertion:- Net torque about point B is of all real forces is not zero. Reason:- Because it will rotate about point B.

The torque about the point 3veci-vecj+3veck of a force 4veci+2vecj+veck through the point 5veci+2vecj+4veck is

A force F= 2hati+3hatj-hatk acts at a point (2,-3,1). Then magnitude of torque about point (0,0,2) will be

A particle having mass m is projected with a velocity v_(0) from a point P on a horizontal ground making an angle theta with horizontal. Find out the torque about the point of projection acting on the particle when It is just about to hit the ground back ?
