Question
Question: Find the tension in the string. 
The tension in the string T=W, (W=m×g)
T=m×g
Where T- the tension in the string
W- weight of the object hung by the string (N)
m - the mass of the object hung by the string
g - acceleration due to gravity (g=9.81×s2m)
Complete answer:
We are going to find the tensions of the string T1,T2.
To find the tension T1,m1=2kg
T1=m1×g
T1=2×9.81
T1=19.62N
The tension of the string T1=19.62N
To find the tension T2,m2=5kg
T2=m2×g
T2=5×9.81
T2=49.05N
The tension of the string T2=49.05N
From the above calculations, we found that the tensions of the string as a result.
T1=19.62N,T2=49.05N
Note: For example, if we stretch the rubber bands, it undergoes tensile force and causes tension in the rubber band. The tensile strength of the material is defined as the ability of the material by which it can sustain the maximum amount of load when being stretched. These calculations can be used in constructions and manufacturing industrial components, The tension of the string, rope, or chain during acceleration is T=W±m.a. For the object goes upward,T=W+m.aand for the object goes downward, T=W−m.a.
