It is merely an outcome of the right-handed coordinate system. In left-handed coordinate system, torque=f cross r

bcoz torque is a vector quantity nd if we will keep f*r then value of sin will be changed.......

nd here  is tkn as a base as it is cnstnt throughout........nt it is the frce whch is responsible fr rotation.

so is that by convention that they took it so? or something else?we could have also taken it as F X
R from the beginning and measure the angle from F to R.. assuming it to be anticlockwise.
