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.

R from the beginning and measure the angle from F to R.. assuming it to be anticlockwise.
