Answer: [M T-2].
- A [M L T-2]
- B [M T-2]
- C [M L-1 T-2]
- D [M L2 T-2]
Correct answer: B. [M T-2]
Explanation: Surface tension is force per length = [M L T-2] / [L] = [M T-2]. It has the same dimensions as spring constant and surface energy per area.
The 7 SI base units. All derived units (newton, joule, watt, volt, etc.) can be expressed as combinations of these 7 fundamental units raised to various powers.
