Use dimensional analysis to determine the dependence of the period T of
a simple pendulum on its mass m , weight w , length l and arc-length of
The Attempt at a Solution
T =cst * malbgcsd
okay im making a mistake here aren't I? by including the arc-Length? i do not know why i should not include it? some one explain? im a bit confused... after this I'll be able to go on.
then i will equate the exponents and solve it.
EDIT: Thanks in advance
