Question

A boy pulls a toy having two carriages placed on a frictionless table by applying a force of one.5 newton

Answer 1

Since, Both blocks are joined by an inxetable string. It can be treated as a Single object with mass of = m1+m2= 0.06kg by each having Same Accletraion.

Now,
F/0.06 kg
= 1.5 cos3/0.06=21.6m/s^2


Then,
Carriage 1, Fcos 30- T = m1a
Thus T= 0.43 ( apporax)
