Q. If the units of mass, length and time are doubled, unit of angular momentum will be
A) Doubled
B) Tripled
C) Quadrupled
D) 8 times the original value
Explanation
$P_{1} = \lbrack ML^{2}T^{- 1}\rbrack$ $D_{2} = \lbrack(2M)(2L)^{2}(2T)^{- 1}\rbrack$ $P_{2} = 4\left\lbrack ML^{2}T^{- 1} \right\rbrack = 4P_{1}$
