Physical World, Units and Measurements
A
Work and torque
12%
B
Angular momentum and Planck’s constant
20%
C
Tension and surface tension
56%
D
Impulse and linear momentum
12%
Solution:
$[$ Tension $]=\left[ M L T ^{-2}\right]$
$[$ Surface Tension $]=\frac{\left[ M L T ^{-2}\right]}{[ L ]}=\left[ M L ^{0} T ^{-2}\right]$
