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.

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
