Sir,
A simple pendulum has a length L. The inertial and gravitational masses of the bob are m1 and m2 respectively. Then the time period of the simple pendulum is given by
T = 2(pie)[m1L/m2g]^(1/2) {Read as 2 pie root m one L by m two g)
My question is that the ratio of inertial mass to gravitational mass is one, so why does m1 and m2 appear in the expression? Also, why do we put m1 in the numerator and m2 in the denominator? What I mean is that why couldn’t it have been in the following way,
T = 2(pie)[m2L/m1g]^(1/2)
Here the g is acceleration due to gravity and pie = 3.14 and the symbol ^ represents power.
