Question

Express the effective length 'L' of a simple pendulum in terms of time period 'T' and g:
(a)L=T²g/4π² (b)L=4π²/gT²
(c)L=2π/g√T (d)L=g√T/2π​

Answer 1

Answer:

ok

Explanation:

Express the effective length 'L' of a simple pendulum in terms of time period 'T' and g:

(a)L=T²g/4π² (b)L=4π²/gT²

(c)L=2π/g√T (d)L=g√T/2π

Answer 2

Answer:

T=2π

g

l

Dimensionally [T]=

[LT

−2

]

[L]

=[T]

As in the above equation, the dimensions of both sides are same. The given formula is dimensionally correct.
