The dimensional symbol of tension in a string is expressed as

L T\(^{-2}\)

M\(^2\) L\(^{-1}\) T\(^{-2}\)

M L T\(^2\)

M L T\(^{-2}\)

The tension \( T \) in a string is defined as the force acting along the string. The dimensional formula for force is given by:

\([T] = [F] = [M^1 L^1 T^{-2}]\)

Thus, the dimensional symbol of tension in a string is:

\([T] = [M L T^{-2}]\)
