We know that,   $$F-f=m$$ aHere, for small body,   $$a1=20-0.2$$×$$3$$×$$103$$⇒  $$a1=143$$ $$ms-2Similarly$$,  $$0.2$$×$$3$$×$$10=10$$×$$a2$$⇒  $$a2=610=0.6$$ $$ms-2$$

A 3 kg block is placed over a 10 kg block and both are placed on a smooth horizontal surface. The coefficient of friction between the blocks is 0.2. If a horizontal force of 20 N is applied to 3 kg block, accelerations of the two blocks (in ms^-2) are (Take, g = 10 ms^-2) [EAMCET 2013]
