Answer 2

GiveN :-

• Identify the dimensional formula of the momentum.

a) [M¹L¹T-¹] b) [M¹L¹ T¹]

c) [ML⁰T-¹] d) [M⁰L⁰T-¹]

SolutioN :-

We need to find the dimensional formula of momentum. We know that momentum is product of Mass and velocity .

So the dimensional formula of velocity and mass are ,

$\sf\dashrightarrow \pink{ Momentum\gray{(p)}= mass \times velocity }\\\\\sf\dashrightarrow Formula_{(Dimensional_p)} = [M^1 L^0 T^0]\times [M^0 L^1 T^{-1}] \\\\\sf\dashrightarrow Formula_{(Dimensional_p)} =[M^{(1+0)} L^{(1+0)}T^{(-1+0)} ] \\\\\dashrightarrow \underset{\blue{\sf Option \ (a)}}{\underbrace{\boxed{\pink{\sf Formula_{(Dimensional_p)} = [M^1L^1T^{-1}] }}}}$
