Question

given figure shows three cubes A,B,C of mass 35kg 5kg and 20kg respectively resting on a smooth horizontal surface initially. the cubes are in contact with each other. A horizontal force of 300N is then exerted on cube A . Calculate the acceleration of cube B and resultant force acting on it
options are
acceleration =3m/s^2 and force =15N
acceleration =4m/s^2and force =20N
acceleration =5m/s^2and force =25N
acceleration =6m/s^2 and force =30N​
