MCQ

Given below are two statements :
Statement $(I) :$ Planck's constant and angular momentum have same dimensions.
Statement $(II): $Linear momentum and moment of force have same dimensions.
In the light of the above statements, choose the correct answer from the options given below :

A
Statement I is true but Statement II is false
B
Both Statement I and Statement II are false
C
Both Statement I and Statement II are true
D
Statement I is false but Statement II is true

Answer

${[h]=ML^2 T^{-1}}$
${[L]=ML^2 T^{-1}}$
${[P]=MLT^{-1}}$
${[\tau]=ML^2 T^{-2}}$
$($Here $h$ is Planck's constant, $L$ is angular momentum, $P$ is linear momentum and $\tau$ is moment of force$)$
