A force F pulls two trolleys A and B, connected by a chain, where the mass of B is twice the mass of trolley A.
It is given that the acceleration of trolley B is 4 m.s⁻² to the right.
How does the acceleration of trolley A compare to that of trolley B? Explain your reasoning.
For which of the two trolleys in the normal force equal to the weight of the trolley? Explain.
