in gravitation i have read that...
the force on a planet towards radius is given by
GMm/r^2
OK.
and the force which acts radially outwards is
Mv^2/r
There is no outward force.
so dunno where the net force acts... !!!:{
The only force acting is gravity.
and torque = F X R
if the direction of net force is towards center then it makes and angle of
180 degrees which gives ex. torque = 0 as sin 180 = 0 ....
Good.
