A cylinder rests in a supporting carriage as shown. The side AB of carriage makes an angle $30^{\circ}$ with the horizontal and side BC is vertical. The carriage lies on a fixed horizontal surface and is being pulled towards left with a horizontal acceleration ‘a’. The magnitude of normal reactions exerted by sides AB and BC of carriage on the cylinder be $N_{A B} and N_{B C}$ respectively. Neglect friction everywhere. Then as the magnitude of acceleration ‘a’ of the carriage is increased, choose the correct statement:

A boy pulls a toy having two carriages placed on a frictionless table by applying a force of $1.5$ newton at $30^{o}$ in a vertical plane. Calculate (i) the acceleration of the $40 g$ carriage, (ii) the acceleration of the $20 g$ carriage and (iii) the tension in the string fastened between the two carriages.
