Consider three blocks of masses m₁ , m₂ ,m₃ interconnected by strings which are pulled by a common force F on a frictionless horizontal table as in the figure. The tension T₁ and T₂ are also indicated

a) T₂ > T₁ if m₂ > m₁
b) T₂ = T₁ if m₂ = m₁
c) T₂ > T₁ always
d) acceleration of the system $=\frac{\mathrm{F}}{{\mathrm{m}}_1+{\mathrm{m}}_2+{\mathrm{m}}_3}$
