The acceleration and tension will be 2.80 m/s² and 19.62 N respectively.
The tension force is described as the force transferred through a rope, string, or wire as it is pulled by opposing forces.
The tension force is applied along the whole length of the wire, pulling energy equally on both ends.
The tension in the string is found as;
T= m₂g-m₁g
T=(m₂-m₁)g]
T=(7 -5) ×9.81
T=19.62 N.
The acceleration in the string is found as;
T=ma
19.62=7 ×a
a=2.80 m/s²
Hence,the acceleration and tension will be 2.80 m/s² and 19.62 N respectively.
