Question

What are the dimension of quantity l√l÷g l bein the length and g the acceleration die to gravity

Answer 1

Explanation:

_/l÷g

dimensional formula of length is :- m

dimensional formula of g is :- kg .m/s^2

so dimesional formula of _/l÷g is

_/s^2/kg =s/ [(kg)^1/2]

so dimension of _/l÷g is 1/2 and 1 in mass and time respectively... [M^1/2 L^0 T^1]
