Question

If velocity \(V\), energy \(E\), and time \(T\) are chosen as fundamental quantities, then dimensional representation of surface tension in this system will be

• A. \(E^1V^{-2}T^{-2}\)
• B. \(E^1V^{-1}T^{-2}\)
• C. \(E^{-2}V^{-1}T^{-3}\)
• D. \(E^1V^{-2}T^{-1}\)

Hint:

In dimensional analysis with new fundamental quantities, assume the required quantity as \(E^aV^bT^c\), then compare powers.

Answer 1

The Correct Option is A
