 Quote by dreamz25 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.
