Answer :
The pair of equations that could be used to find the tensions is given as
m3a3 = Tb & m2a2 = Ta - Tb
How do we find tensions in a string?
To find the force of tension in a string, we use the formula T = mg + ma.
We know that tension is described as the pulling force transmitted axially by the means of a string, a rope, chain, or similar object, or by each end of a rod, truss member, or similar three-dimensional object; tension might also be described as the action-reaction pair of forces acting at each end of said elements.
If the three boxes are pulled to the left by strings with negligible mass on a horizontal surface, the masses of the boxes are m1, m2, and m3, where m3>m2>m1. If the acceleration of the system and the pulling force are known, the we have the tension equation is given as m3a3 = Tb & m2a2 = Ta - Tb.
