comperesion type a solid sphere of mass m and radius r is placed over a plank of same mass m.there is sufficent friction between sphere and plank to prevent slipping. 1.when horizantal force f is applied the acceleration of plank is a.f/9m,b.2f/9m,c.f/3m,d.2f/3m 2.force of friction between sphere and plank is a.f/9,b.2f/9m,3.f/3,d.2f/3 and also find acc of centre of mass of sphere
