The dimensional symbol of tension in a string is expressed as
A
L T\(^{-2}\)
B
M\(^2\) L\(^{-1}\) T\(^{-2}\)
C
M L T\(^2\)
D
M L T\(^{-2}\)
Verified Correct Answer: D.
Step-by-Step Mathematical Solution
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:
\([T] = [M L T^{-2}]\)
