Question

On a horizontal smooth surface, 2 kg block is placed castward and 4 kg block is placed westward. Two blocks are now connected with a horizon tal string. If 12 N horizontal force is applied on 4 kg block along west direction, find (i) common acceleration of two blocks. (1) tension in the string.
